Suppose Milk of Magnesia is a suspension of magnesium hydroxide in water. A common medicine, it is frequently used as an antacid for the reason that it neutralizes hydrochloric acid in the stomach:
Mg(OH)2(s) + 2 HCl(aq) ? Mg2+(aq) + 2 H2O(l)
Compute the mass of HCl that is neutralized by 0.9 g of Mg(OH)2(s).
