First you need to find out the amount of drug in the 8 mL that you would need, at the concentration of 5 mg/1 mL


5 mg/1 mL= x mg / 8 mL

x=40 mg drug needed

then you take that and use the stock solution to find out how much volume would you need with that amount of drug:

100 mg/ 2 mL = 40 mg / x mL

x=0.8 mL
