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

Re: Severe difficulties with calculations
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 0.6mlhttp://i620.photobucket.com/albums/t...snroses21.jpg

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 /?
Sorry this is not an answer but more of a clue as to how you may understand the process.Real stupidity beats artificial intelligence every time.
