Dear Michael,
According to Newton’s equation and his assumption that for spherical objects, you can make the simplifying assumption that the entire object’s mass is concentrated at the centre of the sphere. So mass of the Earth is 6,000,000,000, 000,000,000,000,000 kilograms (6 x 1024 kilograms, or 1.3 x 1025 pounds)
It is “more proper” to ask about mass rather than weight because weight is a force that requires a gravitational field to determine. You can take a bowling ball and weigh it on the Earth and on the moon. The weight on the moon will be one-sixth that on the Earth, but the amount of mass is the same in both places. To weigh the Earth, we would need to know in which object’s gravitational field we want to calculate the weight. The mass of the Earth, on the other hand, is a constant.
I hope this answer is clear
Thanks
Ahmed
