According to the law of conservation of mass, the total mass of the reactants must equal the total mass of the products.

Given that the total mass of the product, mercuric oxide (HgO), is 433.2 grams, the total mass of the reactants (the mercury and oxygen) must also be 433.2 grams.

Therefore, the total mass of the mercury and oxygen on the reactants side of the equation is:

433.2 grams
