A 211 g sample of barium carbonate, BaCO3,
reacts with a solution of nitric acid to give bar- ium nitrate, carbon dioxide and water. If the acid is present in excess, what mass and volume of dry carbon dioxide gas at STP will be produced
BaCO3 + 2HNO3 ==> H2O + CO2 + Ba(NO3)2
mols BaCO3 = grams/molar mass
Using the coefficients in the balanced equation convert mols BaCO3 to mols CO2.
Now convert mols CO2 to grams. g = mols x molar mass.
Convert mols CO2 to L. L = mols x 22.4.
