Question

In metal sulphate, sulphate is 24%.Calculate equivalent weight of metal.
1)76
2)152
3)38
4)304

Answer 1

Metal oxide contains 60% metal (M) and 40% O.

Hence, 60% M reacts with 40% O to produce MO

Now, equivalent wt of O is = atomic wt / valency = 16 / 2 = 8

let equilvalent wt of M be x

40% reacts with - 60%

eq mass 8 reacts with - eq. mass x

cross multiplying, we get x = 60 *8/ 40 = 12

Hope it helps ☺
