Experiment to determine empirical formula

Calculating the Empirical Formula of Magnesium Oxide

Measurements to be made:

Mass 1: Mass of crucible

Mass 2: Mass of crucible and magnesium before heating

Mass 3: Mass of crucible and magnesium after cooling

Magnesium + Oxygen → Magnesium Oxide

The increase in mass is due to magnesium reacting with oxygen to form magnesium oxide

Mass 2 - Mass 1 = Mass of Magnesium

Mass 3 - Mass 2 = Mass of Oxygen

Find how many moles of magnesium and oxygen there are

Find the ratio between the two of them in order to calculate empirical formula
