A student is given a collection of small, irregularly shaped granite stone chips. She wishes to determine the density of granite using a displacement method in a laboratory.
Write down the equation used to calculate density.
Describe an experimental procedure to determine the density of the granite. Your description should explain how to measure both the mass and the volume of a group of the stone chips, including the names of the measuring instruments used.
State one precaution that should be taken specifically during the volume measurement to ensure that the final result is as accurate as possible.
