- The density of a liquid can be calculated by dividing the mass over volume
- A graduated cylinder can measure a liquid's volume
- A balance can measure a liquid's mass
- Hence, density can be measured using a graduated cylinder and a balance

- Density can be measured using a graduated cylinder and a balance
- Density can be used to predict whether a liquid will float on water or sink under water
- Therefore, a graduated cylinder and balance can be used to predict whether a liquid will float on water or sink on water

Therefore, a graduated cylinder and balance can be used to predict whether a liquid will float on water or sink on water
Question
A student has a liquid that does not mix with water. To predict whether the liquid will float on water or sink beneath it, which tools should be used to examine the liquid?
