Write down the desired dilution in the form of a proportion--for example, 1:20 dilution, also known as the dilution factor. Sciencing Video Vault Convert the dilution factor to a fraction with the first number as the numerator and the second number as the denominator.

A solution 20 times more concentrated would be denoted as 20x and would require a 1:20 dilution to restore the typical working concentration. Example: A 1x solution of a compound has a molar concentration of 0.05 M for its typical use in a lab procedure. A 20x stock would be prepared at a concentration of 20*0.05 M = 1.0 M.

To make a 1 to 5 dilution you mix 1 part of your substance with 4 parts water. ie: Mix 1 tablespoon of creamer with 4 tables spoons of coffee, and the coffee is 1/5 creamer now.

Best Answer: you bring a volume of the number on the left of the proportion to a total volume given on the left. For example in the 1:10 you can take 1 uL of X and dilute to a total of 10uL ( add 9 uL of diluent ) , or in the same proportion take 100uL of X and dilute to a total of 1000( add 900 uL of diluent.

1. You need to make a 1:5 dilution of a solution. You need 10 ml of the diluted solution. How much initial sample and diluent should you use? Answer: 1:5 dilution = 1/5 dilution = 1 part sample and 4 parts diluent in a total of 5 parts. If you need 10 ml, final volume, then you need 1/5 of 10 ml = 2 ml sample.

It's a common mistake to add too much solvent when making the dilution. Make sure you pour the concentrated solution into the flask and then dilute it to the volume mark. Do not, for example, mix 250 ml of concentrated solution with 1 L of solvent to make a 1-liter solution!
