Preparing solutions for biochemical experiments

In preparation for a protein purification experiment, you have been asked to prepare 100 mL of an aqueous solution of Tween20. The solution should have a final concentration of 4.25% (v/v) Tween 20. There is a bottle of Tween 20 (100% v/v) on the lab shelf. Describe the method that you will use to prepare the solution.
