Using the Newton's law of gravitation, mass of earth was found for which the formula is:

F = G m1 m2 / r 2

Where F is force, G is gravitational constant, m1 and m2 are the masses of two bodies attracting each other and r is the radius.

For mass of earth the formula will be = g r2 / G

G and g are gravitational constant and value of gravity of earth while r is the radius of earth. Putting values
m = 5.96 × 10 raise to power 24 kg

I think it is roughly 5.97×1024 kg. It is calculated by observing a falling object. According to the force of gravity the time it takes an object to fall a known distance is proportional to the mass of the object exerting the gravitational pull. If you want to learn more about gravity and its effects search for Isaac Newton.
