The key to solving this problem is to found how much the weight of glycerol needed to make the solution. The calculation would be:

weight= volume* concentration
weight1= weight2
volume1 * concentration1 = volume2 * concentration2
200ml * 20%= volume2 * 100%
volume2= 200ml * 20/100
volume2= 40ml

Calculate how much glycerol you would need to make 200 ml of a 20% (v/v) glycerol solution. (Glycerol is a liquid and the initial concentration is 100%).
