Percent Concentrations deal with the amount (in mass of volume) of solute found within a given solution. 

Mass and Volume Concentrations

Concept #1: Mass/Volume Percent Concentration

Example #1: A solution was prepared by dissolving 13.5 g of KNO3 in sufficient water to produce 85.0 mL of solution. What is the (m/v) % of this solution?

Concept #2: Volume Percent Concentration

Example #2: A 750.0 mL bottle of Listerine contains 150 mL of ethanol. What is the (v/v) % of this Listerine cleaning solution?

Practice: How many mL of ethanol are contained in a 750.0 mL bottle of wine that contains 11.0% (v/v) of ethanol?

Practice: Calculate the grams of solute needed to prepare the following: 450 mL of a 2.0% m/v KOH solution.

Practice: What is the mass/volume percent concentration of the following solutions: 0.075 mol sucrose (C12H22O11) in 270 mL of solution.

Practice: The pain reliever ibuprofen is sold as an oral suspension for children 2-11 years of age. How many milligrams would you obtain in a 2.7 tsp dose if it contains 100 mg per 5 mL? (1 tsp = 5 mL)
