Container A contains argon gas at 0C and pressure 380mmHg. Container B of volume 700 ml contains neon gas at 25C and pressure of 3atm. Both of these gases are placed in a 2L vessel at 273K and the total pressure is 1.46atm. What is the volume of container A?

Answer 1

PV = nRT; solve for n = number mols Ar + Ne in the 2L vessel at the conditions listed.

PV = nRT in container B; solve for n = number of mols Ne.

Subtract total mols - mols Ne to give you mols Ar.

Then PV = nRT in container A; You have P, n, R, T; solve for V at the conditions listed.
