**How do you make a 20 fold dilution science.answers.com**

Sciencing.com For example, a 1:20 dilution converts to a 1/20 dilution factor. Multiply the final desired volume by the dilution factor to determine the needed volume of the stock solution. In our example, 30 mL x 1 ÷ 20 = 1.5 mL of stock solution.... You could do the dilutions in one step, or you might have to do serial dilutions. > There is a limit to how much you can dilute a sample in one step. You probably wouldn't want to dilute by more than a factor of 100 in a single step, because that would give you a large volume of dilute solution. Rather, you would use the serial dilution technique.
