(A) In the compound $X_2O_3$,the valency of $X$ can be determined from the formula.Since $O$ has a valency of $2$,in $X_2O_3$,$X$ must have a valency of $3$.Equivalent mass is defined as $\frac{\text{Atomic mass}}{\text{Valency}}$.Given atomic mass of $X = 91.5$.Equivalent mass of $X = \frac{91.5}{3} = 30.5$.
