Question
Exactly 1.0 L of hydrogen gas (H2) is collected over water at 292 K under a total pressure
of 152 torr. If the vapour pressure of water is 16.5 torr at this temperature, what is the
mole fraction of hydrogen in the gas sample?
Volume of CO2 = L

Volume of CO2 = L
Mole
Answers
vp H2O = 16.5 so XH2O = 16.5/152 = ?
152-16.5 = PH2 so XH2 = 135.5/152 = ?
152-16.5 = PH2 so XH2 = 135.5/152 = ?
