Definition for View source for Dilution factor

Ratio of final volume/aliquot volume (final volume = aliquot + [[Diluent]]). 

=== '''To calculate a dilution factor:'''  ===

Remember that the dilution factor is the final volume/aliquot volume. 

<u>EXAMPLE:</u> ''What is the dilution factor if you add 0.1 mL aliquot of a specimen to 9.9 mL of diluent?'' 

#The final volume is equal the the aliquot volume plus the diluent volume: 0.1 mL + 9.9 mL = 10 mL 
#The dilution factor is equal to the final volume divided by the aliquot volume: 10 mL/0.1 mL = 1:100 dilution (10<sup>2</sup>)

<br>The Concentration Factor for this problem = aliquot volume/final volume = 0.1/(0.1 + 9.9) = 0.01 or 10<sup>-2</sup> concentration
