    the equation is:
    C6H12O6 > 2C2H5OH + 2CO2, I know that I put the desired product is on the top, in my notes it says use 1 mol, so would that be the mass of C2H5OH, or
    2C2H5OH. Thanks

    work out the rmm of the useful product, i.e. add up all of the relative atomic masses for the useful product formed

    find the rmm mass of all of the reactants.

    divide the useful product by the mass of the reactants

    multiply by 100% to give you the percentage atom economy

    Oh and if you have a big 2 in front of it then you work out the rmm of the compound then multiply it by two i think.

    I think I haver to multiply by 2, because if I left it the equation won't be balanced, but my notes say 1mol so I'm confused, but I'm gonna go ahead and X2 anyway. thanks for replying.
