## What is the measure of the amount of material in an object and depends on the number of and kind of atoms that compose it?

Mass is a measure of the amount of material in an object, directly related to the number and type of atoms present in the object. Mass does not change with a body's position, movement or alteration of its shape unless material is added or removed. The unit of mass in the SI system is the kilogram (kg).
