If 2.5 grams of citric acid (H3C6H5O7) reacts, how many grams of carbon dioxide will be generated?

1 answer

2H3C6H5O7 + 9O2 ==> 12CO2 + 8H2O

mols citric acid = grams/molar mass
Convert mols citric acid to mols CO2 using the coefficients in the balanced equation. That/s ?mols citric acid x (12 mols CO2/2 mol cit acid) = ?

Now convert mols CO2 to grams. g = mols x molar mass.BTW this is called the theoretical yield.
