"What is the equivalent mass of an element? " Is the question correct? If yes, then explain your answer.

Explanation

The question is not correct because the equivalent masses of the elements are not constant. Equivalent mass of an element depends on particular reaction. If the element utilises its different valencies in different reactions then its equivalent mass will also be different for different reactions.
For example equivalent mass of Cu in `Cu_(2)O ` is 63.5 whereas in CuO, it is 31.75. because in `Cu_(2)O` valency of Cu is 1 and in `CuO`, valency of Cu is 2. according to the relation, equivalent mass=(atomic mass+valency), equivalent mass changes with valency. so, the compound in which the element under consideration is present should be mentioned while calculating the equivalent mass of the element.
