In a chemical reaction, the mass of the reactants is equal to the mass of the products according to the law of conservation of mass.
In this case, you have 30 grams of calcium carbonate (CaCO₃) as the reactant. When it decomposes, it produces carbon dioxide (CO₂) and calcium oxide (CaO).
Since the total mass of the products must equal the total mass of the reactants, the total mass of the products is also 30 grams.
So, the correct response is:
**30 grams**
