A seashell, composed largely of calcium carbonate, is placed in a solution of HCl. As a result, 1700 mL of dry CO2 gas at STP is produced. The other products are CaCl2 and H2O. Based on the information, how many grams of CaCO3 are consumed in the reaction? The density of CO2 at STP = 1.997 g/L (STP stands for standard temperature and pressure).
