Question

What volume of sample, in mL, would be needed to make 2 mL of a 5-fold dilution? (3 significant figures needed)

Answer 1

0.400 mL

Step-by-step explanation:

Hello, the dilution factor (in folds) is given by:

`folds=(total_(volume))/(sample_(volume))`

Thus, the sample volume with three significant figures is given by:

`sample_(volume)=(2mL)/(5`

Best regards.
