Empirical formula is the simplest form.

Answer 2

Answer:
`XY_2`

Step-by-step explanation:

Molecular formula is the chemical formula which depicts the actual number of atoms of each element present in the compound.

Empirical formula is the simplest chemical formula which depicts the whole number of atoms of each element present in the compound.

Given Molecular formula is
`X_4Y_8` , where in the ratio of atoms X and Y is 4: 8.

Thus the simplest ratio of atoms X and Y will be 1: 2.

The empirical formula will be
`XY_2`.
