Question: Solid calcium carbonate reacts with hydrochloric acid solution according to the following reaction: CaCO3 + 2HCl -----> CaCl2 + CO2 + H2O If 120 mL

Solid calcium carbonate reacts with hydrochloric acid solution according to the following reaction: CaCO3 + 2HCl -----> CaCl2 + CO2 + H2O If 120 mL of hydrochloric acid solution, which is 26.2% by mass and has a density of 1.13 g/mL, is added to a 40.0-g sample of solid calcium carbonate, what will be the molarity of hydrochloric acid in solution when the reaction is complete? (Assume the volume of the solution remains constant.) Atomic masses: Carbon = 12; oxygen = 16; calcium = 40; chlorine = 35.5; hydrogen = 1
