  1. mols NaHCO3 - grams/molar mass
    Use the coefficients to convert moles NaHCO3 to mols CO2.
    mols CO2 = mols NaHCO3 x (3 mol CO2/3 mol NaHCO3) = mols NaHCO3 x (3/3) = ?
    Convert mols CO2 to grams. g = moles x molar mass. This is the theoretical yield of CO2.
    You can't do percent yield unless you have the actual yield in the problem and you just didn't post that part.
    %yield = (actual yield in g/theoretical yield)*100 = ?

    Or have I misinterpreted the problem? You want to calculate theoretical yield and you have percent yield?

  3. Follow my instructions to calculate theoretical yield, then plug the actual yield you have into the second equation I wrote to obtain % yield.
