Question

a student needs to calculate the density of some liquid. the student knows that density is equal to mass divided by volume. Name two tools the student could use to measure the liquid in order to calculate its density. Explain what a student should measure with each tool.

Answer 1

The student can measure a liquid's volume by using a graduated cylinder, or a beaker. Mass can be measured by first weighing an empty container on a scale, and then by adding the liquid to the container and weighing it again.

Answer 2

A measuring cylinder and a weighing balance.

Step-by-step explanation:

The density of a liquid is equal to mass divided by its volume, therefore we need to find two things: mass and the volume.

To find the mass, a container should first be weighed empty and then with the liquid inside it. The difference in their weights will be the mass of the liquid.

For the volume, a measuring cylinder or a beaker can be used to measure it.

Dividing these values of the mass by the volume will give the density of the liquid.
