A solution with 8.35 g of a non-electrolyte solute in 50.0 g naphthalene (Kfp = 6.90°C/m) freezes at 76.5°C. Pure naphthalene freezes at 81.0°C. What is the molar mass of the solute?

Answers

Answer 1

The molar mass of the solution is obtained as 257 g/mol.

What is the molar mass of the solute?

We know that the molar mass of the solute is something that we can be able to obtain from the formula for the change in the temperature of the substance.

Thus;

ΔT = K m i

ΔT =  temperature change

K = freezing constant

m = molality

i = Vant Hoff factor

Then we have;

ΔT =  81.0°C - 76.5°C = 4.5°C

Thus;

4.5°C =  6.90 * m * 1

m = 4.5/6.90

m = 0.65

Then;

m = mass/molar mass/ Mass of solution in kilograms

0.65 = 8.35/M * 1/50 * 10^-3

M = molar mass

0.65 * 50 * 10^-3 * M =8.35

M = 8.35/0.65 * 50 * 10^-3

M = 257 g/mol

The density of grain alcohol is 0.789 g/mL. Given that the density of water at 4 C° is 1.00 g/mL, what is the specific gravity of grain alcohol? Enter your answer in provided box.

Answers

Density and specific gravity are related but not the same, Specific gravity is defined as the ratio of the density of a substance to the density of a reference substance. In this case, the reference substance is water, and it is commonly assumed to be water at 4°C (39.2°F) and is generally given as 1.000 g/cm3 (or 1.000 g/ml).

So, the specific gravity of grain alcohol = Density of grain alcohol / Density of water at 4°C = 0.789 g/mL / 1.00 g/mL = 0.789.

This value is dimensionless and it is used to compare the density of different substances with water.

Answers

The observed appearance of the cells after adding the 10% NaCl is likely due to the hypertonicity of the solution.

hypertonicity refers to a solution that has a higher solute concentration than the cell, causing water to flow out of the cell and the cell to shrink and become dehydrated. This can also be observed as the cells appear to be wrinkled and contracted.This can cause water to move out of the cell due to osmosis, resulting in the cell becoming dehydrated and shrinking. This is the opposite of hypotonicity, which is a solution with a lower solute concentration, causing water to move into the cell, causing the cell to swell. In biological systems, hypertonicity can cause cells to lose function or even die if the condition is severe or prolonged.

The complete proton balance for the system is:

NaHSO3 + H2O <=> Na+ + H3O+ + HSO3-

HSO3- + H2O <=> H+ + SO32- + H2O

NaHSO3 + H2O <=> Na+ + H3O+ + H+ + SO32-

What is the nucleophile ?

Nucleophiles are atoms or molecules that carry a negative charge and have the ability to form an electron-pair bond with a positive or partially positive atom. Common nucleophiles include hydroxide ions (OH–), amines (H2N–), and carboxylates (RCOO–). Nucleophiles are important in many organic reactions, such as substitution, elimination, and addition reactions. They are also important in biochemistry, where they facilitate enzyme-catalyzed reactions such as hydrolysis, oxidation, and reduction. In biochemistry, nucleophiles can attack the carbonaly carbon of an organic molecule, resulting in a covalent bond known as an ester or amide bond.

If you are not 100 percent sure, then please dont answer.Passage 1(adapted from A Bit of Green from Melchior's Dream and Other Tales by Juliana Horatia Ewing)Children who always live with grass and flowers at their feet, and a clear sky overhead, can have no real idea of the charm that country sights and sounds have for those whose home is in a busy, manufacturing towna town, in fact, as I lived in when I was a boy, which is more than twenty years ago.My father was a doctor, and we lived in a comfortable house. I was born and raised there; and, ever since I could remember, the last sound that soothed my ears at night and the first to which I awoke in the morning, was the eternal rumbling and rattling of the carts and carriages as they passed over the rough stones. I never noticed if I heard them in the daytime, but at night my chief amusement, as I lay in bed, was to guess by the sound of the wheels what sort of vehicle was passing."That light, sharp rattle is a horse-drawn cab," I thought. "What a noise it makes and gone in a moment! One gentleman inside, I think. There goes a light cart; that's a carriage by the way the horses step." And the cart came so slowly that I was asleep before it had got safely out of hearing.Ours was a very noisy street, but the noise made the night cheerful; and so did the clock tower near my house, which struck every quarter of an hour; and so did the light of the street lamps, which came through the blinds and fell upon my little bed. We had very little light, except street light and daylight; sunshine rarely found its way to us, and, when it did, people were so little used to it that they pulled down the blinds for fear it should hurt the carpets. In the room that my sister Minnie and I shared, we always welcomed the sunshine with blinds rolled up to the very top; and as we had no carpet, no damage was done.Passage 2(adapted from The Wind in the Willowsby Kenneth Grahame)The Mole had been working very hard all morning, spring-cleaning his little home. First, with brooms, then with dusters, then on ladders and steps and chairs, with a brush and a pail of whitewash, till he had splashes of whitewash all over his black fur, an aching back and tired arms. Spring was moving in the air above and in the earth below and around him, entering even his dark and little house with its spirit of discontent and longing. It was small wonder, then, he suddenly flung down his brush on the floor and bolted out of the house without even waiting to put on his coat. Something up above was attracting his attention, and he climbed through the steep little tunnel filled with gravel to reach the street owned by animals who lived in houses that received plenty of sunlight and air. So, he scraped and scratched and scrabbled and again scrabbled and scratched and scraped, working busily with his little paws and muttering to himself, "Up we go! Up we go!" till at last, his snout came out into the sunlight, and he found himself rolling in the warm grass of a great meadow."This is fine and so much better than whitewashing!" he said to himself.The sunshine struck hot on his fur, soft breezes soothed his heated brow, and after the loneliness of the little cellar he had lived in so long, the carol of happy birds fell on his dulled hearing almost like a shout. Jumping off all his four legs at once, in the joy of living and the delight of spring without its cleaning, he pursued his way across the meadow till he reached the hedge on the further side."Hold up!" said an elderly rabbit at the gap."Sixpence for the privilege of passing by the private road!"He was bowled over in an instant by the impatient and silly Mole, who trotted along the side of the hedge, looking funnily at the other rabbits as they peeped hurriedly from their holes to see what the noise was about."Onion-sauce! Onion-sauce!" he remarked jokingly, and he was gone before they could think of a thoroughly satisfactory reply.Then they all started grumbling at each other. "How strange you are! Why didn't you tell him" "Well, why didn't you say" "You might have reminded him" and so on, in the usual way, but, of course, it was then much too late, as is always the case. 1.4-8 a car weighing 130 kn when fully loaded is pulled slowly up a steep inclined track by a steel cable (see figure). the cable has an effective cross-sectional area of 490 mm2, and the angle a of the incline is 308.
