    If you know the mole ratio between the ketone and the borohydride, this set of instructions will do it. I can help with any part of the problem except the equation.

    I found two references that contradict each other.
    One shows R2C=O + 2H^- ==> R2CHOH and the other shows
    R2C=O + H^- ==> R2CHOH (one H supplied by the hydride and the other by hydrolysis of the intermediate alkoxide salt.
