Question

law of conservation of mass

Answer 1

mass can neither be created nor destroyed.
It can be converted from one form to the another.
The amount of mass in the universe is constant

Answer 2

The Law of Conservation of Mass says that mass can neither be created nor be destroyed in any chemical reactions. In other words, Law of conservation of Mass states in any chemical reactions the total mass of products is equal to the total mass of reactant.

For better concept, I would like to solve a question on this topic.

Q. If 5.3 g of Sodium Carbonate react with 6 g of Ethanoic acid and formed 8.2 g of Sodium Ethanoid, 2.2 g of Carbon dioxide and 0.9 g of Hydrogen. Show that this data Verify the law of Conservation of Mass :-

Sodium Carbonate + Ethanoic acid ----> Sodium Ethanoid + Carbon dioxide +Hydrogen

Put the given value :-

5.3 g + 6 g --> 8.2 g + 2.2 g + 0.9 g
=> 11.3 g = 11.3 g

Hence,
Mass of reactant = Mass of Products.

This data is associated with the Law of Conservation of Mass because this law says that in a chemical reactions, the total mass of reactant is equal to the total mass of products.

Hence,
Law of conservation of Mass is Verified.
