What is gravitational force?
The gravitational force exists as a force that seduces any two objects with mass. We call the gravitational force engaging because it consistently tries to pull masses together, it never makes them apart. Every object, including you, exists dragging on every other object in the entire universe. Gravity exists calculated by the acceleration that it provides to freely falling objects. On Earth's surface, the acceleration of gravity exists at about 9.8 meters (32 feet) per second squared.
Let mass be X
Force= mg
Mass=force/gravitational force
X=45/9.8
Therefore, X or Mass is 4.5.
Gravitational force of mercury= 3.7
1 N = Kg m/s²
4.5 X 3.7= 16.65
