Bru

a substance has a vapor pressure of 35.0 mmHg at 52.0 degrees Celsius and 70.0 mm Hg at 77.0 degrees Celsius. What is the heat of vaporization for this substance?

Determine the lattice energy for CaBr2 if the enthalpy of solution for CaBr2 is -145 kJ/mol, and the heats of hydration for Ca2+ and Br- are -1650 kJ/mol and -292 kJ/mol respectively.

A 250.0 mL sample of an aqueous solution at 25 degrees Celsius contains 35.8 mg of an unknown nonelectrolyte compound. If the solution has an osmotic pressure of 11.25 mmHg, what is the molar mass of the unknown compound? a.) 237 g/mol b.) 484 g/mol c.) 3...

calculate the standard molar entropy change for the combustion of methane gas using S naught values from standard thermodynamic tables. Assume that liquid water is one of the products.

All real numbers less than 69

Compare and contrast the traits of viruses and bacteria. Is a virus considered a living thing?

Record yourself saying the following conjugated verb forms in the past tense for the verb DAR

Which of the following events could decrease competition for resources in an ecosystem?

So you invert the equation to M=pi/RTi to solve for Molarity. I plug in the numbers ((0.1480 atm)/(0.08206 L atm/K mol)(298K) (1)) That equals 6.1554*10^-4 mols. Dont you divide 0.358g/6.1554*10^-4??

What do you mean solve for molar mass? I think that is the problem that I am having.

nevermind, I got it. Is the answer 160 g/mol?

True

10/11, 9/10, 8/9, 7/8

Are you really that lazy

Thanks I got a 100%

Bru they change the question like #1 might be the same as yours but question 2 will be diffrent jsyk

Detroit is here to help idiot

is this correct or no...

BOBBY IS A W

yes is correct

the answer is 7/8 pls dont ask the bot math questions he will be wrong
