To an evacuated vessel with movable piston under external pressure of 1 atm and 0.1mole of He and 1 mole of an unknown compound (vapour pressure 0.68 atm at `0^(@)`C) are introduced. Considering the ideal behaviour, the volume (in litre) of the gases at `0^(@)`C is close to:

Text Solution

Verified by Experts

The correct Answer is:
7
`V = (nRT)/p = (0.1 xx 008 x 273)/(1-0.68) =7`
