Pharmacists sell tablets containing magnesium hydroxide, Mg(OH)2, to combat indigestion. A student carried out an investigation to find the percentage by mass of Mg(OH)2 in an
indigestion tablet. The student reacted the tablet with dilute hydrochloric acid. Mg(OH)2(s) + 2HCl(aq) MgCl2(aq) + 2H2O(l)
The student found that 32.00 cm3 of 0.500 mol dm–3 HCl was needed to react with the Mg(OH)
in a 500mg tablet. [1g = 1000mg].
(i) Calculate the amount, in mol, of HCl used.
