WebSep 7, 2024 · What is the dilution factor in scientific notation? The dilution factor is the inverse of the dilution. (Inverse means you flip the two numbers of the fraction; with scientific notation you use the positive exponent.) For a dilution of 1/2, the dilution factor would be 2/1 or 2. 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 ...
