Problem- You carefully weigh out 19.00g of CaCO3 powder and add it to 76.95g of HCl solution. You notice bubbles as a reaction takes place. You then weigh the resulting solution and find that it has a mass of 88.16g. The relevant equation is

CaCO3(s)+2HCl(aq)?H2O(l)+CO2(g)+CaCl2(aq) Assuming no other reactions take place, what mass of CO2 was produced in this reaction?
