Question

$A,E,M$ and $n$ are the atomic weight, equivalent weight, molecular weight and valency of an element. The correct relation is:

• A. $A=E\times n$
• B. $A=\frac{M}{E}$
• C. $A=\frac{M}{n}$
• D. $M=A\times n$

Answer 1

The correct option is A $A=E\times n$

For an element, the atomic weight is equal to the product of equivalent weight and valency.
$A=E\times n$
In the other word, the equivalent weight is the ratio of atomic weight to valency
$E=\frac{A}{n}$
