I can use compound measures for density.
Lesson details
Key learning points
- Density can be calculated by dividing the mass by the volume of the solid.
- The units for mass and volume determine the units for density.
- By rearranging the formula, you can calculate either mass or volume.
Common misconception
Giving a density answer in the wrong units.
Read the question carefully and check the units of the mass and the volume. It may be necessary to convert between metric units.
Keywords
Density - The density of a substance is measured as the substance's mass per unit of volume.
