A 1.247 g piece of aluminum metal is placed in 63.5mL of 0.2054M sulfuric acid solution and reacts in a single displacement reaction. The hydrogen gas product is collected by displacement of water into a container that has a temperature of 26.0 C and whose gas pressure is set equal to barometric pressure of 769.4 torr. Calculate the number of moles of the hydrogen gas produced during the reaction, then calculate the volume that hydrogen gas would occupy at STP.
