I did this for you already
A 1.0kg mass weighs 9.8 Newton on earth's surface, and the radius of Earth is roughly 6.4 x 10 to the power of 6. The mass of the earth is 6.02 x 10 to the power of 24. Calculate the average density of Earth?

Mass over volume:
rho = 6.02 * 10^24 * 10^18 / [(4/3) pi 6.4^3]
