Discussion of all aspects of biological molecules, biochemical processes and laboratory procedures in the field.

Moderator: BioTeam

why are you calculating with the molecular weigth? Just use the percentage

c2 [%] = (1%*0.6ml)/40.6ml

Cis or trans? That's what matters.

let's say, you will add 2 ml of 5% solution to 98 ml, OK?

So it will be
2 ml * 5% = (98+2) ml * c2 [%]
c2 = 0.1%
