Lesson Plan: Percentage ConcentrationChemistry • First Year of Secondary School
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to express and calculate the percentage concentration of a solution by its volume or mass ratio.
Objectives
Students will be able to
- explain how a solution can be defined as a percentage by volume or mass,
- explain the difference between percentage concentration by volume and by mass,
- recall and use equations to calculate percentage concentration by volume or mass,
- calculate the percentage by volume (% (v/v)) or mass (% (m/m)) of a solution,
- calculate the percentage by volume or mass when two different percentage solutions are mixed together,
- calculate the percentage mass by volume, % (m/v), of a solution.
Prerequisites
Students should already be familiar with
- solutions,
- percentages.
Exclusions
Students will not cover
- molar concentrations,
- mole fractions.
