What mass of magnesium is needed to produce hydrogen gas

What mass of magnesium, in reaction with an excess of hydrochloric acid, is needed to produce 128ml of hydrogen(H2) gas? The H2 gas is collected over water at a temperature of 25 degrees Celcius and a total pressure (PBR) of 762 mmHg. The ideal gas law constant R = 0.0821L*atm/K*mol.
