Question

prove that A=EV where a= atomic mass, V=valancy, E=equivalent mass​

Answer 1

• Equivalent weight is the mass of one equivalent, that is the mass of a given substance which will combine with or displace a fixed quantity of another substance.

• Equivalent mass = Valency/ Atomicmass

• The equivalent weight of an element or radical is equal to its atomic weight or formula weight divided by the valence it assumes in compounds. The unit of equivalent weight is the atomic mass unit ; the amount of a substance in grams numerically equal to the equivalent weight is called a gram equivalent.
