Total pressure of a mixture of H2 and O2 is 1.00 bar. The mixture is allowed to react to form water, which is completely removed to leave only pure l-l2 at a pressure of 0.35 bar. Assuming ideal gas behaviour and that all pressure measurements were made under the same temperature and volume conditions, the composition of the original mixture is
  • a)
    a
  • b)
    b
  • c)
    c
  • d)
    d
Correct answer is option 'B'. Can you explain this answer?

Correct answer is option B
Avagadro′s Law says:
Equal volume of two gases at same pressure and temperature conditions have equal number of molecules.
∴1 O2 molecule consumes 2 H2 molecules.    
∴Since after the reaction only H2 is left,  we know all of O2 is consumed.
∴This implies what all consumed 1/3 of it was O2.
Hence, O2 in the mix was at a partial pressure of (1 - 0.35)* 1/3 = 0.22
And rest was H2 = (1 - 0.22) = 0.78
Hence oxygen- hydrogen composition in the original mix was:0.22 bar O2 and 0.78 bar H2.
