As shown above, the dilution can be expressed as a fraction (1/100), in scientific notation (10-2) or, less commonly, as a decimal (0.01). In this example, water is the diluent (a general term for the liquid used to dilute the sample).

WebJan 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. WebOne situation in which the dilution factor is important to consider is when the original sample has been pre-diluted relative to the standard sample.
