The empirical formula is CaSO₄.

The empirical formula tells us the simplest whole-number ratio of the different types of atoms in a compound.

We know that the molecular formula of calcium sulfate is CaSO₄.

To get the empirical formula, we divide the subscripts by their highest common factor (1).

This gives you the empirical formula CaSO₄.
