Ptotal = PdryH2 + PH2O
Look up vapor pressure H2O @ 24 C. That goes in for PH2O
Find total pressure. That comes from the barometer reading for thr pressure of the air in which the gas is collected.. Substitute and solve for pressure of the dry hydrogen gas.

look up water vapor pressure at 24C. Subtract that from atmospheric pressure. The answer is then pressure of H2 collected (without water)
