1. Calculate the mass of magnesium that is required to produce 27.8 mL of hydrogen gas at 26 °C and a total pressure of 735 mmHg when collected over water according to the following reaction. Use the table of vapor pressures of water given in the lab procedure to correct for the water vapor. Mg (s) + 2 HCI (aq) MgCl2 (aq) + H2 (g) Balance the following equation and calculate the volume of hydrogen gas produced from the reaction of 0.425 g of aluminum when completely reacted with excess hydrochloric acid. The gas was collected over water at 28 °C and a total ressure of 745 torr. Al (s) + HCl (aq) AlCls (aq) + H2 (g)
