How would you make 120 mL of a 1 to 25 dilution of a yeast extract?...
How would you make 120 mL of a 1 to 25 dilution of a yeast extract? I'm really not understanding this process so steps/explanations would be nice. Thanks.
Homework Answers
1 to 25 dilution means that 25ml solution contains 1ml of the yeast extract.
120/25=4.8ml
120ml-4.8ml=115.2ml
Therefore to make 120ml of 1 to 25 dilution of yeast extract, take 4.8ml yeast extract and mix it with 115.2ml water or the solvent that you intend to use.
