When a reaction mixture with a total volume of 1720 mL that contains 0.605 L of gaseous CO2 measured at STP dissolved in 940 mL of water was stoichiometrically produced as per the balanced equation, how many mol of solid CaCO3 were required?

H2SO4(aq) + CaCO3(s) → CO2(g) + CaSO4(s) + H2O(l)
.605L/22.4L=moles CO2
mol CaCO3=molCO2
