13. (d) Pharmacists sell tablets containing magnesium hydroxide, Mg(OH),, to combat indigestion. A student caried out an investigation to find the percentage by mass of Mg(OH), in an indigestion tablet. The student reacted the tablet with dilute hydrochloric acid. Mg(OH),(s) + 2HC{aq) → MgCL(aq) + 2H,0() The student found that 32.00 cm³ of 0.500mol dm 3 HClwas needed to react with the Mg(OH)2 in a 500 mg tablet. [1g = 1000 mg]. (i) Calculate the amount, in mol, of HCL used. mol amount = (i) Determine the amount, in mol, of Mg(OH), present in the tablet. amount = mol (iii) Determine the percentage by mass of Mg(OH), present in the tablet. answer =
