Magnesium reacts with hydrochloric acid to form hydrogen gas according to the equation below. If sufficient hydrochloric acid is used to react completely with 72.9 g of magnesium, calculate how many moles of hydrogen gas (H2) will be produced. Use the stoichiometry road map to first convert the mass of Mg into moles of Mg
