Required practical 5: Density: Part 2 - Calculating the density of a irregularly shaped object

Question 1

Outline the basic steps of the practical

Answer 1

1) Measure the mass of the irregular shape.
2) Fill a displacement can with water and submerge the object.
3) Record the volume of water that has been displaced with a measuring beaker.
4) Calculate the density from the mass and volume.

Question 2

What should you place under the can spout to collect the water?

Answer 2

A measuring beaker.

Question 3

Explain how you should fill the displacement can to get the most accurate results

Answer 3
