You need to make a stock of 75% glycerol for archiving phage samples. You locate the undiluted glycerol stock on the shelf. How would you prepare 50ml of the desired glycerol concentration?
Homework Answers
We need to make a stock of 75% glycerol, which means in 100 ml 75ml will be glycerol and 25 ml will be water. In order to make 50ml of the desired solution 37.5ml (75*50/100) of glycerol will be added and 12.5ml (50-37.5) of water will be added.
If glycerol existed in a powdered form then for 75% of glycerol -75g will be glycerol powder and 100ml will be water and for 50 ml of the desired solution, 37.5g of glycerol and 50ml of water will be added.

You are required to make a solution that contains 50 mmoles of buffer (its molecular mass is 121.1 g/mol), 300 mmoles of sodium chloride (its molecular mass is 58.44 g/mol), and 10% glycerol in a total volume of 0.75 L. Tell me (A) what weight of buffer and NaCl you will need, and (B) what volume of glycerol (diluted from a 100% stock concentration) you will need. Also, (C) what then makes up the additional volume to 0.75 L, and...
