        Determine the equivalent weight of each of the following compounds assuming the formula weights of these compounds are x, y and z respectively. (i)\[N{{a}_{2}}S{{O}_{4}}\]           (ii)\[N{{a}_{3}}P{{O}_{4}}.12\,{{H}_{2}}O\] (iii)\[C{{a}_{3}}{{(P{{O}_{4}})}_{2}}\]

Answer:

                        Eq wt = Mol. wt/Total positive valency of metal atoms (i)\[x/2\]                              (ii)\[y/3\]                             (iii)\[z/6\].
