The everyday definition of weight is a measure of how heavy a person or object it. It measures the mass of a mole of a given substance. In the scope of its subject chemistry occupies an intermediate position between physics and biology.
An object s mass is constant in all circumstances. Weight is the name of the force exerted on an object due to the acceleration of gravity on earth weight is equal to the mass times the acceleration due to gravity 9 8 m sec 2 on earth. However the definition is slightly different in science. What is mass and how is it different from weight.
A unit used for stating atomic and formula weights. Learn how mass is defined when used in the fields of chemistry chemical engineering and physics.
