In the chemical reaction given:
\[ \text{CaCO}_3 \rightarrow \text{CO}_2 + \text{CaO} \]
We can apply the law of conservation of mass, which states that mass cannot be created or destroyed in a chemical reaction. Therefore, the total mass of the reactants will be equal to the total mass of the products.
Since 30 grams of calcium carbonate (CaCO3) are heated, the total mass of the products (carbon dioxide CO2 and calcium oxide CaO) will also be 30 grams.
So, the correct answer is:
**30 grams**
