Some Basic Concepts Of Chemistry

\(\mathrm{Mg}(\mathrm{OH})_2\) is used as an antacid. If a person, suffering from acidity, produces \(2.5 \mathrm{~L}\) of Gastric juice in a day, approximately how many antacid tablets, each containing \(600 \mathrm{~mg}\) of \(\mathrm{Mg}(\mathrm{OH})_2\), will be required to completely neutralise the whole \(\mathrm{HCl}\) produced in the stomach in one day? (Gastric juice contains \(3.0 \mathrm{~g}\) of \(\mathrm{HCl}\) per L). (Atomic masses: \(\mathrm{Mg}=24 \mathrm{~g} / \mathrm{mol}, \mathrm{O}=16 \mathrm{~g} / \mathrm{mol}\) &
\(\mathrm{H}=1 \mathrm{~g} / \mathrm{mol}\).)
