Your lab group is given 20ml of a 20% of a 20%(w/v) glucose solution and an unlimited amount of water. From the starting 20% glucose solution, your group wants to make 100ml of 0.2% glucose solution. Design a two step dilution series so that at the end your group has the desired glucose solution.
Dilution 1: _____ml of 20% glucose + _____ ml of water= _____ ml of _____ % glucose
Dilution 2: _____ ml of Dilution 1 + ______ ml of water= 100 ml of 0.2% glucose
