In a closed system, a chemical reaction takes place. The mass of the reactants in the beginning of the reaction is 25g. What does the mass have to be in the end of the reaction in order to follow the law of conservation of mass?

Explanation:
the weight of the resultant solution will remain same i.e. 25g as law of conservation of mass says that the mass of reactants before the reaction and mass of product formed after the reaction is always same.

' mass can neither be created nor it can be destroyed '
The Law of Conservation of Mass dates from Antoine Lavoisier's 1789 discovery that mass is neither created nor destroyed in chemical reactions.
