Assuming gasoline is 100% isooctane, with a density of 0.692g/mL, what mass of carbon dioxide is produced by the combustion of 1.2x10^10 gal of gasoline (the approximate annual consumption of gasoline in the U.S.)?

Sorry I meant Na2CrO4 and Na2Cr2O7 and basically i need to know if they react exactly the same with different elements
