An easy way to do that is to weigh the object. In principle, the mass can be derived from the weight.
The gravity of an object depends on its mass and the distance between it and another object. The larger the mass of an object and the closer it is to another object, the stronger the gravitational force between them.
it is equal to the mass of the original object
the mass of an object measures the amount of matter in a object.
The center of mass of an object is the point at which its mass can be considered to be concentrated. It is the average position of all the mass in the object. It is the point around which the object will balance in any orientation.
The shape of an object bears no relation to the mass of an object.
The mass of an object in a gravitational field is called the object's "mass".The presence or absence of a gravitational field has no effect on the mass.
An object's mass is constant and does not change, unless additional mass is added or removed. The mass of an object is an intrinsic property.
The amount of matter in an object is mass.
The mass of the object and the velocity of the object.
