(ii) A student was given 400 cm of aqueous ammonia solution, NH, (aq). The student was asked to determine how many moles of NH., had been dissolved to prepare the solution. The student titrated 25.0cm of NH, (aq) and found that it reacted exactly with 32.5cm3 of 0.100 mol dm sulturic acid. The equation for this reaction is shown below. 2NH(aq) + H,SO,(aq) → (NH,SO,(aq) Calculate the amount, in moles, of NH, in the original 400 cm solution.
