Question

How will you prove experimentally the law of conservation of
mass?

Bapan Pathak · Accepted Answer

Hello,
The law of conservation of mass states that during in a physical
or chemical change, the mass of products remains equal to the total
of reactants
For example: When 100g of mercuric oxide is heated, 92 6 g of
mercury and 7 4 g of oxygen are obtained as products i e HgO
â†’ Hg + O2
In this case mass of reactant =100g
Mass of products = Mass of Hg + Mass of O2 = 92 6 + 7
4 = 100g
Thus, we obtain Mass of product = Mass of reactants This
verifies the law of conservation of mass
