State whether the following statements are true or false:
$(i)$ The molarity of a $0.6 \ N$ aqueous solution of ${H_3PO_3}$ is $1.2 \ M$.
$(ii)$ $\text{Empirical formula} = n \times \text{Molecular formula}$.
$(iii)$ In ${Cl_2O}$,the weight of chlorine combining with $8 \ g$ of oxygen is $35.5 \ g$.

(A) $(i)$ False. For ${H_3PO_3}$,the basicity is $2$. Therefore,$\text{Normality} = \text{Molarity} \times \text{Basicity}$. $0.6 = M \times 2$,so $M = 0.3 \ M$.
$(ii)$ False. The correct relation is $\text{Molecular formula} = n \times \text{Empirical formula}$.
$(iii)$ True. In ${Cl_2O}$,$2 \times 35.5 \ g$ of ${Cl}$ combines with $16 \ g$ of ${O}$. Thus,$35.5 \ g$ of ${Cl}$ combines with $8 \ g$ of ${O}$.
