Sulphur forms the chlorides ${\mathrm{S}}_2{\mathrm{Cl}}_2\mathrm{and}{\mathrm{SCl}}_2.$ The equivalent mass of sulphur in ${\mathrm{SCl}}_2$ is

 The atomic weight of Sulphur = 32

In ${\mathrm{SCl}}_2$ valency of Sulphur = 2

So equivalent mass of Sulphur in $SC{l}_2$  = $\frac{32}{2}=16$

Similarly , In ${\mathrm{S}}_2{\mathrm{Cl}}_2$ Valency of Sulphur = 1

So equivalent mass of Sulphur in ${\mathrm{S}}_2{\mathrm{Cl}}_2$ = $\frac{32}{1}=32$
