Question
CaCO3(s) + 2 HCl(aq) --> CaCl3(aq) + H2O(l) + CO2
It takes 19.26 mL of 0.6721 M HCl to completely react with the CaCO3. What is the mass of CaCO3 in the tablet?

First correct the formula for calcium chloride to CaCl2.
mols HCl required = M x L = ?
mols CaCO3 = 1/2 that from the coefficients.
grams CaCO3 = mols CaCO3 x molar mass CaCO3
mols HCl required = M x L = ?
mols CaCO3 = 1/2 that from the coefficients.
grams CaCO3 = mols CaCO3 x molar mass CaCO3
