A 20.0% (m/m) solution means there are 20 grams of solute per 100 grams of solution. Since the solution is made up of solute and solvent, for every 20 grams of solute, there are 80 grams of solvent. To find the amount of solute in 40 grams of solvent, a simple proportion can be set up: 20g solute / 80g solvent = 10g solute / 40g solvent. This shows that a 20.0% (m/m) solution will always contain 10.0 g of solute per 40.0 g of solvent.
