you carefully weigh out 14.00g of CaCO3 powderand add it to 56.70 g of HCl solution. You notice bubbles as a reaction takes place. You then weight the resulting solution and find that it has a mass of 64.96 g. The relevent equation is CaCO3 + 2HCl = H2O + CO2+CaCl2. Assuming no other reactions take place. what is the mass of CO2 produced
