take 1 ml, add 9 ml water.
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
what is dilution rate for glycos
10 as a percentage of 2 is 500% but 2 as a percentage of 10 is 20%
20% is 2 out of 10 as a percentage.
It is: 10/40 = 25% as a percentage
110
2 times dilution from 100% acetone
Add one part of the substance you want to dilute to nine parts water. Nine parts water plus one part substance is 10 parts. If you add one part substance to 10 parts water, you get an 11-fold dilution.
By 10-fold dilution
Yes
Add 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
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.
1 in 25. (10/250)
10
An 8-fold dilution means you are making your solution 1/8 less concentrated. So, if you want to make 100 ml of a solution diluted 8 fold you would do as follows: 1/8=.125 100*.125= 12.5 Mix 12.5 mL of your concentrated solution with 87.5 mL of your solvent (water etc..) to bring the final volume to 100 mL. If you wanted to perform a ten fold dilution you would simply mix 10 mL of your concentrated solution with 90 mL of your solvent. 1/10=.1 100*.1=10
It is a mixture of 1 part of the active ingredient (by volume) to 10 parts of the solvent.
You add 9.09ml of stock solution to a volumetric and make it up to 1 litre to get a 110 dilution
