Mass balance relies on the conservation of mass principle. By doing mass balance the materials entering and leaving the system and mass flows can be identified which are unknown at the beginning. According to the conservation law, mass cannot disappear or be created spontaneously.
The boundaries of the system cover all of the liquid and constituent flows into and out of the system. The control volume is used to identify the actual volume in which change is occurring.
