A sample of magnesium metal reacts completely with water via the following reaction: Mg (s) + 2 H2O (l) → Mg(OH)2 (aq) + H2 (g) The hydrogen produced is collected over water at 25.0°C. If the volume of the gas is 7.80L and the pressure is 0.980 atm, calculate the mass of magnesium metal reacted. (Pwater @ 25.0°C = 23.8 mm Hg)
