Magnesium hydroxide, Mg(OH)₂, is commonly used as the active ingredient in antacid tablets. A student analysed an antacid tablet for mass percent Mg(OH)₂ by dissolving a tablet weighing 1.462 g in 25.00 mL of 0.953M HCl, and neutralizing the unreacted HCl. The neutralization required 12.29 mL of 0.602M NaOH. Calculate the mass percent of Mg(OH)₂ in the antacid tablet.
