It takes 2 moles of HCl to react with each mole of Mg.
48.6 g of Mg = ? moles
150.0 g of HCl = ? moles
If there are less than half as many moles of Mg as HCl, it will be the limiting reagent.
When magnesium metal and an aqueous solution of hydrochloric acid combine, they produce an aqueous solution of magnesium chloride and hydrogen gas. Using the equation, Mg (s) + 2HCl (aq) → MgCl2 (aq) + H2 (g), if 48.6 g of Mg and 150.0 g of HCl are allowed to react, identify the limiting reagent
