QUESTION 3 (a) Ammonium sulphate, (NH),50, is a soluble salt and it is used in agriculture as fertiliser. 5 g of ammonium sulphate is dissolved in 1 litre of water to produce ammonium sulphate solution. (Relative atomie mass: H = 1, N = 14,0 = 16, ) Calculate

(1) the number of inoles of dissolved ammonium sulphate

(ii) the number of molecules present in the ammonium sulphate solution.

(iii) the number of positive ions present in the ammonium sulphate solution

(iv) the number of negative ions present in the ammonium sulphate solution

(v) the total number of ions present in the ammonium sulphate solution​
