Question

how we find the equivalent mass​

Answer 1

Answer:

The con­cept of an equiv­a­lent ex­ists in chem­istry. The equiv­a­lent of a sub­stance, or as it is also called, the equiv­a­lent quan­ti­ty of a sub­stance, means the quan­ti­ty of a sub­stance which in­ter­acts with one mole of hy­dro­gen. Equiv­a­lent mass­es may be re­quired for cor­rect cal­cu­la­tions in a chem­i­cal re­ac­tion be­tween sub­stances. The ad­van­tage is that we can ob­tain a cor­rect val­ue with­out long for­mu­las of chem­i­cal re­ac­tions, be­cause we only have to know that the chem­i­cal sub­stances in­ter­act to­geth­er, or that the sub­stance is the prod­uct of a chem­i­cal re­ac­tion.
