CaCO3 + 2HCl ==> CaCl2 + H2O + CO2
mols HCl = M x L = ?
mols CaCO3 = 1/2 that (see the coefficients in the balanced equation).
grams CaCO3 = mols x molar mass = ?
A Rolaids tablet contains calcium carbonate to neutralize stomach acid. One Rolaids tablet requires 44.55 mL of 0.448 M hydrochloric acid to convert its calcium carbonate into calcium chloride, carbon dioxide and water. How many grams of calcium carbonate are there in one Rolaids tablet?
