Lesson: Percentage Concentration Chemistry • First Year of Secondary School

In this lesson, we will learn how to express and calculate the percentage concentration of a solution by its volume or mass ratio.

Lesson Plan

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.
