For the following chemical equation:

CaCO3(s) + 2HCl(aq).......>H2)(l) +CO2 (g) +CaCl2 (aq)

A). How many liters of CO2 can form at STP when 18.5 mL of a3.51 M HCl solution reacts with excess CaCO3?

B). What is the molarity of a HCl solution if the reaction of210 mL of the HCl solution with excess CaCO3 produces 12.1 L of CO2gas at 725 mmHg and 18 C?
