This is the chemical salt 'Ammonium sulphate'.
It is usually written as ' (NH4)2SO4
The (NH4)2 moiety tells us that there are '2'(two) ammoniums present.
Since ammonium is made up of NH4 , then there are two(2) nitrogen (N) present and there are eight(8 = 4 x 2) hydrogen(H) present.
The SO4 moiety tells us that there is one(1) sulphur (S) and there are four(4) oxygen present.
Unlike the ammonium moiety there is no doubling of the sulphate moiety.
Ammonium sulphate is a agricultural fertiliser.
