This resource is a basic worksheet on working with concentration for Grades 9 to 10. It introduces the concentration formula, shows students how to rearrange it to solve for concentration, moles, and volume, and includes a worked example to model the process clearly.

The worksheet gives students practice with:

• finding concentration from mass and volume
• finding volume from concentration and mass
• finding mass or moles from concentration and volume
• converting between cm³ and dm³
• converting between mass and moles using molar mass

It also includes an answer key so students can check their work or teachers can use it for review. This resource can be used for classwork, homework, extra practice, or revision.
