Bit of a clumsy question that. Don't know how to put it.
I mean if you've got 100ml of a liquid you know something has an absorption rate of, say, 1mg/10ml and something else has a rate of 1mg/20ml do you just figure them both out and add them together like this (when they're going into the same liquid):
first: 1mg/10ml. Fluid: 100ml Therefore 10mg of substance.
second: 1mg/20ml. Fluid: still 100ml Therefore 5mg of substance.
So I can say now I've got those two substances within that 100ml of liquid, in those proportions?
I've got 100ml of liquid and it contains 10mg of substance A and 5mg of substance B.
Seems obvious that's the way it would be but I thought I'd ask. What's seems obvious to me often turns out to be wrong..
