To an evacuated vessel with movable piston under external pressure of – InterviewSolution

1.	To an evacuated vessel with movable piston under external pressure of 1 atm, 0.1 mole of He and 1.0 mole of an unknown compound (V.P. = 0.68 atm at 0^(@)C) are introduced. Considering the ideal gas behaviour, the total volume (in L) of gases at 0^(@)C is close to ..... .
Answer» SOLUTION :As the piston is movable, the GAS pressure is 1 ATM. `THEREFORE p_(He) = 1-0.68 = 0.32` atm. Apply pV = nRT for He.
