Answer to Question #173085 in General Chemistry for Brenda

Question

Susie started with 100g of calcium carbonate. At the end of the reaction there was 56g left in the test tube. Calculate the mass of carbon dioxide made

Answer 1

100-56 = 44g

1mol CaCO3 = 1molCO2

Molar Mass CaCO3 = 100g/mol

44g CaCO3 = 44g/100g/mol = 0.44mol

0.44mol CO2 made

Molar Mass of CO2 = 44g/mol

Mass of 0.44mol CO2 = 0.44×44

= 19.36g CO2 made
