How can I calculate the dilution factor using concentration?

Jan 26, 2016· Rearrange to get the volumes of the two solutions. V 1 = n c1 and V 2 = n c2. This means that the dilution factor will be. D.F. = V 2 V 1 = V 2 ⋅ 1 V 1 = n c2 ⋅ c1 n. D.F. = c1 c2. Since the concentration of the stock solution is higher than the concentration of the diluted solution, you can express the former as a multiple of the latter.
