. To an evacuated vessel with movable piston under
external pressure of 1 atm., 0.1 mol of He
and 1.0 mol of an unknown compound (vapour pressure 0.68 atm. at 0ºC ) are introduced.
Considering the ideal gas behaviour determine the total volume (in litre) of the gases at 0ºC
A: 7 L
B: 9 L
C: 4 L
D: 2.3L
Best Answer
Explanation :
Vapoure pressure due to the compound = 0.68 atm
Final Answer :
Hence the final answer is option A.i.e. 7L.
