Serial Dilution A Level Biology PAG 4.2
I'm doing PAG 4.2 which is the effect of enzyme concentration on the rate of reaction and I don't understand how to do the serial dilutions to get the other concentrations of Trypsin. We're meant to start by putting 2 cm^3 milk powder in each tube. Then put 2cm^3 of 2.00% trypsin solution in the first tube and then dilute it to get 1.00%, 0.50%, 0.25% and 0.13% but I'm confused about how to go about this.
