    Ok, I'm doing GCSE OCR CHEM at the moment...so I only know percentage yield!

    Percentage Yield = ACTUAL YIELD divided by PREDICTED YIELD

    Atom economy = (mass of useful product/total mass of reactants) x 100
    Percentage yield=(Actual yield/maximum possible yield) x 100
    Theoretical percentage yield (I presume you mean maximum possible yield by this as well??) can be calculated in a reacting masses calculation.
