A piece of magnesium reacts with an aqueous solution of HCl to produce H2 gas. The hydrogen gas is collected over the HCl solution at a temperature of 22.0°C. If the total pressure of the system is 0.965 atm, and the volume of gas collected is 780. mL, what are the partial pressure and the mass of H2 produced? (You may assume that the dissolved HCl has no effect on the vapor pressure of water, which is 19.8 torr at 22.0°C.)
