Answer:

The empirical formula is the simplest whole-number ratio of atoms in a compound.

The ratio of atoms is the same as the ratio of moles. ...

Mass of Mg = 0.297 g.

Mass of magnesium oxide = mass of Mg + mass of O.

0.493 g = 0.297 g + mass of O.

Mass of O = (0.493 – 0.297) g = 0.196 g.

There is 1 mol of Mg for 1 mol of O .
