Magnesium reaction with Oxygen

Magnesium reaction with Oxygen.

Crucible with the lid on was weighted, mass 1 – 18.43g.

Magnesium inside the crucible with the lid on was weighted, mass 2 – 19.09g.

Mass 2 (crucible with lid and magnesium inside) – 19.09g

Mass 3 (crucible with lid and magnesium oxide inside) – 19.44g

Mass of the oxygen = mass 3 – mass 2

This shows that if 48g of Mg would react with 32g of O2 then the maximum yield would be 80g of MgO.

If 48g of Mg produces 80g of MgO, than 1g of Mg produces: 80.6
