Explanation / Answer

(1) The volume of oxygen will be less than the volume of hydrogen

The number of moles of hydrogen will be double the number of moles of oxygen

H2O --------> H2 + 1/2 O2

(2) lower , slower

(3) Ptotal = PH2 + PH2O

=> PH2 = 771 - 17.54

=> PH2 = 753 mm Hg

(4) Three significant figures

(5) 1.01 atm

(7) n = PV/RT

=> n = (773/760) x 0.4656 / 0.0821 x 303.35

=> n = 0.019 mol

=> mass of H2 = 0.038 g
