Describe an experiment that can be done to prove the law of conservation of mass?

Explanation:

Given alka - seltzer and a flash, students design and conduct an experiment to prove the law of conservation of mass.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
