Calculation Question...

Hiya,

Just wondering. If you have 1 mole of a drug, with a RMM of 84. How do you find out its % mass/weight?


I would have thought that you use the: moles=mass/rmm

Which goes to 1 x 84 = 84. Then divide that by 100?

= 0.84%

Any suggestions as to the right answer will be much appreciated.

Thanks.

What's your biopharmaceutics module like? Mine doesn't have any equations or calculations - it's all theory on drug delivery.

hmm, its quite a lot, they have spent the whole year teaching - receptor theory (agonist, antagonist stuffs), thermodyanmics, rate of degradation (shelf life, half life, finding the extra conc to increase the shelf life), the henderson hasselbalch eqn and related, acid-base calculations, arrhenius, 1st, 2nd, zero order eqns, clearence. thats about it, i may have missed a lot out as i haven't gone thru them yet

That sounds like the physical pharmacy module we had to do in the first year. It was horrible and far too hard!

so are you suggesting that as you move up the year, things get eaiser? - or rather, more relevent and interesting
