Simple Dilutions Make a 1:10 dilution (say this as “a one in ten dilution”) Take 1 part of your stock solution and add 9 parts of solvent (usually water but sometimes

Another way is to dilute the stock 1/10 twice and then perform a further 1/100 dilution: 1/10 x 1/10 x 1/100 = 1/10,000 dilution This would yield 100 ml of a 1/10,000 dilution of stock in water

So if 50 mL of a solution con- taining 10 g of active ingredient with a strength of 20 or 1 : 5 w/v is diluted to 100 mL, Page 3 the original volume is doubled, but

milligram = mg = 1/1000 of a g or 10-3 g gram = g 1:5 dilution (verbalize as "1 to 5" dilution) entails combining 1 unit volume of diluent (the material to be Making fixed volumes of specific concentrations from liquid reagents: V1C1= V2C2

Slide 1 Laboratory Math II: Solutions and Dilutions Philip Ryan, PhD The concentration of a solution is how much of the solute is present per unit of This means that you add 10 milliliters of the 5M NaCl stock solution to a container and

The second “rule” of dilutions/concentrations is an obvious one: there is a limit to 10µl divided by (990 + 10) µl total volume = 10/1000 = 1/100 = 10-2

For example, a sample size of 1 ml is added to 9 ml of diluent to equal a total of 10 ml Example: 1:10 dilution - if the concentration is 1,000 CFU, a one log
