Use the chemical reaction to answer the question. CaCO3→CO2+CaO A scientist heats 30 grams of calcium carbonate (CaCO3 ) in the chemical reaction shown. What is the total mass of the products? (1 point) Responses 60 grams 60 grams 10 grams 10 grams 15 grams 15 grams 30 grams
The total mass of the products can be found by calculating the molar mass of each product and then adding them together.
CaCO3 has a molar mass of 100.1 g/mol
CO2 has a molar mass of 44.0 g/mol
CaO has a molar mass of 56.1 g/mol
When 30 grams of CaCO3 is heated, it will produce:
44 grams of CO2 (2 moles of CO2)
56 grams of CaO (1 mole of CaO)
Therefore, the total mass of the products is 100 grams (44 grams of CO2 + 56 grams of CaO).
