If `W_1 and W_2` are the weights of two reactants in any reaction, having their equivalent weights `E_1 and E_2` respectively, which of the following equations represents the law of equivalence correctly?
(a) `W_1 E_1 = W_2 E_2` (b) `W_1 E_2 = W_2 E_1` ( c ) `W_1 W_2 = E_1 E_2`

Explanation

The answer is (b), because number of equivalents
`= W_1 // E_1 = W_2 // E_2`.
