The chemical reaction shows that the reaction of 1 mole of calcium carbonate (CaCO3) produces 1 mole of carbon dioxide (CO2) and 1 mole of calcium oxide (CaO).
To determine the total mass of the products, we need to calculate the molar masses of carbon dioxide and calcium oxide.
Molar mass of CO2 = 12.01 g/mol (C) + 2 * 16.00 g/mol (O) = 44.01 g/mol
Molar mass of CaO = 40.08 g/mol (Ca) + 16.00 g/mol (O) = 56.08 g/mol
Since the molar ratio is 1:1 for both CO2 and CaO, the total mass of the products will be equal to the molar mass of CO2 plus the molar mass of CaO.
Total mass of the products = Molar mass of CO2 + Molar mass of CaO
= 44.01 g/mol + 56.08 g/mol
= 100.09 g/mol
Therefore, the total mass of the products is 100.09 grams.
Use the chemical reaction to answer the question.
