A 50.0 mL solution of 0.15 M HCI was used to dissolve a 1.45 g of antacid tablet. The 2.09 excess HCl was then )titrated with 22.0 mL of 0.095 NaOH solution. If the active ingredient in the tablet is Mg(OH)2, calculate the mass percent of Mg(OH)2 in the tablet. + Mg (OH) (Molar mass of Mg(OH)2 = 58.3 g/mol) %3D a) 15 % b) 43% c) 22 % d) 11 % e) 4.0%
