(II) A geologist finds that a Moon rock whose mass is 9.28 kg has an apparent mass of 6.18 kg when submerged in water. What is the density of the rock?
We are trying to find the density of the moon rock by submerging it completely in water.
Step 1 of 4
Density of a body is defined as the ratio of the mass of the body to its volume. Mathematically,
Archimedes Principle: Volume of water displaced by the body, is equal to the volume of the immersed part of the body in water.
