WebA dilution factor is simply a multiplier that changes the final analyzed concentration back to the original concentration of the undiluted solution. Dilution factors are simply the ratio of the final volume divided by the original volume: C i = C f [V f /V i], where [V f /V i] is the dilution factor. In Example 2 above, the dilution factor is ...
WebThe original volume of your solution was 2 mL, and the final volume was 12 mL, so the dilution factor is simply 2 12.
