When magnesium metal (Mg) reacts with hydrochloric acid (HCl), magnesium chloride (MgCl2) and hydrogen gas (H2) are produced according to the following chemical equation. 2 HCl (aq) + Mg (s) → MgCl2 (aq) + H2 (g) If 1.44 moles of HCl is consumed in the chemical reaction above, how many grams of HCl are consumed? Molar mass of HCl is 36.46 g/mol.
