The weight of an object, in a gravitational field, is a force that is equal to the mass of the object multiplied by the acceleration due to gravity.
Weight is the vertical force exerted by a mass as a result of gravity.
Weight can be expressed mathematically as
Fw = mg
where,
Fw = force, or weight, resulting from an accelerating object
m = mass of an object
g = acceleration due to gravity
This equation is a variation of Newton's second law of motion. In the general form of the equation the variable g is replaced by the variable a which stands for any acceleration acting on an object with mass. Whenever an acceleration is caused by gravity, the force on that object is called it's weight.
The weight of an object should not be confused with the mass of an object. The mass of an object is constant no matter where in the universe the object is located, but it's weight can vary in different places because the force of gravity can vary depending on location.

Mass.
It is weight changes depending on gravity. Weight can change. The pull of gravity determines an objects weight.
Weight is mass x g, where g is the local gravitational field strength.
Density is defined as the mass of something divided by the volume of the same thing. During a careful reading of the definition, it becomes apparent that density is not mass, and that density is also similarly not weight as well, either.
Yes, Mass remains constant because the definition of mass does not mean weight. Mass means the amount of room and object takes.
