$74.5 \ g$ of a metallic chloride contains $35.5 \ g$ of chlorine. The equivalent mass of the metal is

Assertion : The normality of $0.3 \ M$ aqueous solution of $H_3PO_3$ is equal to $0.6 \ N$.
Reason : Equivalent weight of $H_3PO_3 = \frac{\text{Molecular weight of } H_3PO_3}{3}$

The equivalent weight of a metal is $4.5$ and the molecular weight of its chloride is $80$. The atomic weight of the metal is

When the weights of two elements combine with each other,their ratio is the ratio of their ......
