The student collects H2(g) produced by the reaction and measures its volume over water at 298 K after carefully equalizing the water levels inside and outside the gas collection tube as shown in the diagram below. The volume is measured to be 45.6 mL. The atmospheric pressure in the lab is measured as 765 torr, and the equilibrium vapor pressure of water at 298 K is 24 torr. What is the number of moles of H2 (g) produced in the reaction?.
