Answer #1

Ptotal= PPH2 + PPH2O---> PPH2= 755-24=731torr

PV=nRT

760 torr ----1 atm

731 torr -----x= 0.962 atm

n= 0.962 x 1.55/0.082x298= 0.061 mol H2

    1.Water can be decomposed into its elements by applying an external voltage. Hydrogen gas form sat one electrode and oxygen at the other, according to the following overall equation : 2H2O(l)→2H2(g) + O2(g)The hydrogen gas evolved by this reaction was collected in a water-filled tubeat 25 °C. The water levels were equalized to make the pressure of the trapped gas equal to the ambient pressure.However, the trapped gas is actually a mixture of hydrogen gas and water vapor. The partial...
