You carefully weigh out 19.00 g of CaCO3 powder and add it to 76.95 g 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 88.16 g . 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?
Express your answer to three significant figures and include the appropriate units.
Mass of CO2 produced=18.63g
