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, when 30 grams of calcium carbonate (CaCO₃) is heated, it decomposes into carbon dioxide (CO₂) and calcium oxide (CaO). The total mass of the products will be equal to the mass of the reactants.

Therefore, if the scientist starts with 30 grams of calcium carbonate, the total mass of the products (CO₂ and CaO) will also be 30 grams.

So the answer is:

**30 grams**
