1.4 g of a complex $\left[\mathrm{M}{\left({\mathrm{NH}}_3\right)}_{\mathrm{x}}\right]{\mathrm{Cl}}_{\mathrm{y}}$ (Molecular mass $=268.8$ ) where ' M '(atomic mass $=60.3$ ) is a metal ion was treated with 50 mL of 2 N NaOH solution and boiled. Ammonia gas evolved was passed through 50 mL of $0.5\mathrm{M}{\mathrm{H}}_2{\mathrm{SO}}_4$. After the reaction was over, excess acid required 37.2 mL of 0.5 N NaOH . The value of '( $\mathrm{x}+\mathrm{y}$ )' in the formula is
