<span>The law of conservation of mass states that a mass of an object or the amount of matter composed inside an object or thing will not change unless it is added or removed of the matter that is contained in the object itself.
This means that for example, when you're bag has a mass of a 1kg, and you filled it with clothes it will jump its mass from 1kg to possibly 5kg, hypothetically. Thus, withoout the object or clothes that was added the weight of the bad wouldn't change and vice-versa.

15 protons (atomic number is always the number of protons) 15 electrons because no charge was mentioned so it must be the same as protons 16 neutrons because mass number is the combined number of protons and neutrons
Answer:
10 g/cm3
Explanation:
The density is equal to mass/volume
so Mass is 80g
and volume is 2*3=8
so density=80/8=10g/cm3
