Use the chemical reaction to answer the question.
CaCO↓(3) -> CO↓(2) + CaO
A scientist heats 30 grams of calcium carbonate (CaCO↓(3) ) in the chemical reaction shown. What is the total mass of the products?
60 grams
15 grams
10 grams
30 grams
60 grams
This can be calculated by adding the molar masses of the products: CO2 (44 grams/mol) and CaO (56 grams/mol).
44 grams/mol (CO2) + 56 grams/mol (CaO) = 100 grams
Since the reaction produces equal amounts of CO2 and CaO, the total mass of the products will be 100 grams.
