Thank you. The density of hydrochloric acid is 1.18 g/cm^3, and I thought I needed to use that. I guess I didn't.

1. Determine the volume of 1.50 mol dm–3 of hydrochloric acid that would react with exactly 1.25 g of calcium carbonate. 2. 2HCl(aq) + CaCO3(s) --> CaCl2(aq) + CO2(g) + H2O(1) 3. I tried to do this: (1.25 g CaCO3) / (100 g CaCO3) = 0.0125 moles of CaCO3 2 moles of HCl are needed...
