CaCO3 + 2HCl ==> CaCl2 + H2O + CO2
mols CaCO2 = grams/molar mass
Using the coefficients in the balanced equation, convert mols CaCO3 to mols CaCl2.
Now convert mols CaCl2 to g. g = mols x molar mass.
Carbonates react with acids to form a salt, water and carbon dioxide gas. When 22.1 g of calcium carbonate are reacted with sufficient hydrochloric acid, how many grams of calcium chloride will be produced?
