  • Severe difficulties with calculations

    Anyone know how to work these out? I am not even sure where to start.

    2.5%w/v = 2.5g in 100ml, which equals 2500 mg in 100ml, or 2500000 micrograms/100ml.
    So 250 mcg is in 0.01ml

    20,000iu/ml in one syringe so a 0.7 ml syringe would contain 14,000iu.
    So we now have 14,000iu/0.7ml. We want a volume of that 0.7ml syringe which would contain 12,000iu. The volume is worked out by calculating 0.7/(14,000/12,000) which equals 0.6ml

            Where are these questions? I can't see them.

                y intercept = 1/vmax but to find vmax = 1/yintercept

                gradient = km/vmax

                so km = gradient * vmax.

                the same rearranging is occuring in tboth equations but why is one x and one /?
                Simple algebra: practice with y=mx and find equations for m and x and then using the equations for m and y find the equation for y again (without using a bookor internet or calculator) with regard to this also look up dimensional analysis, its been years since I came across it (something I learnt in physics) but it is a very powerful checking tool to see if you got the formula the right way round.

                Sorry this is not an answer but more of a clue as to how you may understand the process.
