Question

A mixture of hydrogen and oxygen at 1 bar pressure contains 20% by weight of hydrogen calculate the partial pressure of hydrogen

Answer 1

Mixture  contains 20g hydrogen and 80g oxygen.

n H2 = 20/2 = 10 mol and n O2 = 80/32 = 2.5 mol

Mole fraction of H2 is xH2 = 10/12.5

And p H2 = x H2 x p total = 10/12.5 x 1 bar

p H2 =O.8 bar
