The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by its valency.

The unit of equivalent weight is the atomic mass unit.

As, we know Oxygen has an atomic weight of 16 and it always assumes valency 2 in compounds, so its equivalent weight is 8.
And atomic weight of sulphur is 32 and its valency is +2.
Now, formula weight of sulphate =
(atomic weight of sulphur + four times atomic weight of oxygen)
Formula weight of (SO4)= 32+4*(16)
= 96

Therefore, sulphate radical (SO 4) has formula weight 96 and always has valency 2 in compounds.
So, equivalent weight of sulphate(SO4) is 96/2= 48
