### How do you calculate dilution factor? + Example - Socratic

22-03-2014·DF = V f V i. EXAMPLE 1: What is the dilution factor if you add a 0.1 mL aliquot of a specimen to 9.9 mL of diluent? Solution: V f = aliquot volume + diluent volume = (0.1 + 9.9) mL = 10.0 mL. DF = V f V i = 10.0mL 0.1mL = 100. You have diluted the sample by a factor of 100. The dilution factor is often used as the denominator of a fraction.
