A 1.0 kg mass weighs 9.8 N on Earth's surface, and the radius of Earth is roughly 6.4 x 10^6 m. Calculate the average density of Earth

Answer 1

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]

Answer 2

6*5e10
