The total mass of the products is 40 grams (Option C).

In 1789, Antoine Lavoisier discovered that mass is neither created nor destroyed in chemical reactions. This is now known as Lavoisier's law of conservation of mass. In other terms, the sum of the masses of the reactants is equal to the sum of the masses of the products. So, in this case, the total mass of the products must be 40 grams as well.

The total mass of the products is 40 grams.
