∙ 11y agoAdd 2 mL of culture to 20 mL of buffer. 2/20 = 1/10
10 as a percentage of 2 is 500% but 2 as a percentage of 10 is 20%
what is dilution rate for glycos
It is: 10/40 = 25% as a percentage
20% is 2 out of 10 as a percentage.
To find out how many ounces of chemical it would take to make 100 gallons of finished dilution at 0.5%, we can set up a proportion. Since 11 ounces of chemical are used in 10 gallons of water, we can establish the ratio of ounces of chemical to gallons of water as 11:10. By setting up a proportion and solving for x, we find that it would take 110 ounces of chemical to make 100 gallons of finished dilution at 0.5%.
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.
To make a 50% acetone control, you can mix equal parts of acetone and water. For example, if you start with 10 ml of acetone, you would add 10 ml of water to make a 50% acetone solution.
Dilution of acid does not change its chemical properties, so the acid itself is not weaker. However, dilution can reduce the concentration of the acid in a solution, making it less corrosive or less likely to cause harm upon contact.

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
Dilution is the process of reducing the concentration of a substance by adding more solvent. The dilution factor is the ratio of the final volume of the diluted solution to the initial volume of the concentrated solution. It is used to calculate the new concentration after dilution.
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
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
