Dilution factor is the final volume / aliquot volume.
Aliquot volume is the measure of sub volume of original sample. Final volume is the total volume.
Dilution factor =final volume /aliquot vol.
for example ; what is the df when you add 2ml sample to 8m???
total vol is 2+8=10
DF=total vol/aliquot.
10/2=5
So 5 is dilution factor
Concentration factor, CF = 1/Dilution factor, DF if DF = 5 then CF = 1/5 CF = 0.2
There is a formula for the difference of two squares. The sum of two squares doesn't factor.
There is a formula for the "difference of squares." In this case, the answer is (5b - 14c)(5b + 14c)
There is a formula for the "difference of squares." In this case, the answer is (3m + 13n)(3m - 13n)
You need to know density and percent by weight. Then use the following formula: ((1000)density x % by weight) / formula mass=concentration
cfu/ml = (no. of colonies x dilution factor) / volume inoculated
In chemistry and biology, the dilution factor is the total number of unit volumes in which the material is dissolved. As I understand it, the dilution refers to the dilution ratio. If you add 1 part of something to 4 parts of something else, the dilution ratio is 1 to 4. The dilution factor counts all the parts and expresses the same thing as 1 out of 5.
Total count = (cells counted x dilution factor)/(area x depth)
Concentration factor, CF = 1/Dilution factor, DF if DF = 5 then CF = 1/5 CF = 0.2

A dilution ratio is normally used for a mixture of two fluids: an active component and a carrier solvent. The dilution ratio is the ratio of the volume of the solvent to the volume of the active component.
1 in 25. (10/250)
The concentration is the same !
The answer depends on the dilution factor and if the sulfuric acid was 100% to start.
Because you probably used a 2-fold dilution. So you need to multiply your count by 2 to get the ACTUAL amount.
