An unknown mass of a PbCO3 is allowed to react with 200.0 mL of 0.1253 M H2SO4. This forms a solution of PbSO4 and CO2 gas, which is removed via heat. The resulting solution is titrated with 65.20 mL of 0.1344 M NaOH to completely neutralize the excess acid. Calculate the volume of CO2 gas formed by the initial reaction if the density of CO2 at 25 ºC is 1.808 g/L.
