Answer:

FeSO4.

Explanation:

We divide the percentages by the relative atomic masses of the elements:

Iron =  36.76 / 55.845= 0.6583

Sulphur = 21.11 / 32.06 = 0.6584

Oxygen = 42.13 / 15.999 = 2.6333

Simplifying the ratios:

Fe : S : O =

0.6583: 0.6584: 2.6333

= 1 : 1 : 4

The empirical formula is FeSO4.   (Ferrous Sulphate).
