Help with empirical formula for magnesium oxide!

This is the data given:

Mass of crucible: 29.1234g

Mass of crucible + Magnesium: 29.9345g

Mass of crucible + Magnesium oxide: 30.7450g

Obtain the empirical formula from data above.

I keep getting Mg2O3 because it’s a 1:1.52 ratio but I know that the real answer is MgO. What am I doing wrong?
