The mass of the Earth can be described using the gravitational law, specifically Newton's Law of Universal Gravitation, which states:

"Every point mass attracts every other point mass by a force acting along the line intersecting both points. The force is proportional to the product of their masses and inversely proportional to the square of the distance between their centers."

Mathematically, this is expressed as:

F = G * (m1 * m2) / r^2

Where:

F is the gravitational force between the two objects
G is the gravitational constant (6.67408e-11 N m^2 kg^-2)
m1 and m2 are the masses of the two objects
r is the distance between the centers of the two objects

To find the mass of the Earth, we can use the following:

m1 = mass of the Earth (what we want to find)
m2 = mass of an object on the surface of the Earth (such as a person or a rock)
r = radius of the Earth (approximately 6.371e6 meters)
F = weight of the object on the surface of the Earth (which is equal to the gravitational force)

Rearranging the equation to solve for m1 (the mass of the Earth), we get:

m1 = F * r^2 / (G * m2)

Plugging in the values, we can calculate the mass of the Earth to be approximately:

5.972 x 10^24 kilograms

This is the accepted value for the mass of the Earth, which is used in a wide range of scientific and engineering applications.
