I'm sorry I don't have the answer... Did you figure it out? I have the same problem with different numbers. CH390... online.

A household bleach solution contains 5.25% (by mass) NaClO. How many moles of NaClO are needed to make 1000 L of the solution? (density = 1.07g/mL) This is the complete question on my assignment. It's 1000 L.

Argon makes up 0.93% by volumee of air. Calculate its solubility (mol/L) in water at 20C and 1.0 atm. Henry's law constant for Argon under these conditions is 1.5 x 10^-3 mol/L*atm.

Chem
How much heat (in kJ)is required to convert 2.565kg of liquid sulfur dioxide at the boiling point to a gas at 60C? BP of SO2 is -10C and delta H vap is 25.73kJ/mol. Specific heat capacity of the gas is 0.622 J/g*K I don't know what formula to use to calculate this problem??

Chem
The boiling point of ethanol is 78.5C and delta H vap = 40.5kJ/mol. Calculate the vapor pressure (in torr) of ethanol at 0.0C ?

A .326L container holds 0.146g of Ne and an unknown amount of Ar at 30C and the total pressure is 627 mmHg. Calculate the moles of Ar present? (I have calculated temp 308K, pressure is 0.825 atm and moles of Ne are .007) Chem - DrBob222, Wednesday, March 3, 2010 at 3:25pm T i...

Chem
I'm calculating moles of Ar to be 0.0038, however, when plugging this into the online homework program it's marking it as incorrect. Am I doing a step incorrectly or do you get a similar answer? Thanks!
