In a chemical reaction, the law of conservation of mass states that the total mass of the reactants must equal the total mass of the products.

In this case, the reaction is:

\[ \text{CaCO}_3 \rightarrow \text{CO}_2 + \text{CaO} \]

You start with 30 grams of calcium carbonate (CaCO3). When it decomposes, it will produce carbon dioxide (CO2) and calcium oxide (CaO), but the total mass of the products will equal the initial mass of the reactants.

Therefore, the total mass of the products will also be 30 grams.

**Answer:** 30 grams
