The law of conservation of mass states that mass is neither created nor destroyed during a chemical reaction. This can be gleaned from the third postulate in Dalton's series.

Magnesium oxide decomposes into magnesium and oxygen. If 12.09g of magnesium oxide decomposes to form 7.29g of magnesium, what mass of oxygen gas is also released in the reaction?
