Since the mass of an object is a fixed quantity it follows that the mass of an object will be the same on the Earth and on the Moon. On the other hand, the weight of an object is not fixed and depends on the local gravitational acceleration according to the formula W=mg, where W is the weight of the object, m is the mass of the object, and g is the local gravitational acceleration.
If we assume that the object weighs 500 N on the Earth and the Earth has (on average) a surface gravitational acceleration of 9.81 m/s2 then we can calculate the object's mass as follows:
m = W/g = (500 N)/(9.81 m/s2) = 50.0 kg
This would be the mass of the object on the Moon as well.
