The discussion below may help.

Explanation:

Mass is a characteristic property of an object (whose real nature we are only now beginning to understand). It is not dependent of the surroundings of that object.

On the other hand, weight is the manner in which a gravitational field exerts a force based on the mass of an object, so this quantity depends on the location of the object and that of nearby objects (such as the Earth, for example).

In scientific terms, #W=mxxg#

where #g# is the strength of the gravitational field at the location of the mass #m#.

The best way to think of mass is to consider it as the property of an object that resists changes in the motion of the object (its inertia, in other words). Mass is the numerical value given to the inertia of a body.

Think of it like this: in an orbiting space station, a baseball would be weightless, due to its current location and motion. However, it would not be massless, as you would quickly discover if you tried to throw it. You would still require a force to change its motion, because it still possesses mass.
