Dear student,
Ans: Quantity
The law of conservation of mass states: Mass can neither be created nor destroyed in a chemical reaction. According to this law mass of an isolated system will remain constant over time. This means when mass is enclosed in a system and no transfer of material and energy is allowed in or out, its quantity will never change.
