(b)
Answer to Problem 1P
The average density of Earth lies in between the densities of aluminum and iron and the average density of granite is less than the density of the Earth.
Explanation of Solution
The average density of the Earth is
Granite is a type rock that is mostly found on the surface of the earth. Since the value
Conclusion:
Therefore, the average density of Earth lies in between the densities of aluminum and tin and the average density of granite type rocks is less than the average density of the Earth.
