Our chemistry classes are in need of new balances. We are down to three working balances for eleven chemistry classes! We're in dire need of new epquipment! In chemistry to fully understand how balances and scales operate, there must be an understanding of the difference between mass and weight. Mass is a constant unit of the amount of matter an object possesses. It stays the same no matter where the measurement is taken. The most common units for mass are the kilogram and gram. Weight is the heaviness of an item. It is dependent on the gravity on the item multiplied by the mass, which is constant. The weight of an object on the top of a mountain will be less than the weight of the same object at the bottom due to gravity variations. A unit of measurement for weight is the newton. A newton takes into account the mass of an object and the relative gravity and gives the total force, which is weight. Although mass and weight are two different entities, the process of determining both weight and mass is called weighing.
