Question

The equivalent mass of chlorine is 35.5 and the atomic mass of copper is 63.5. The equivalent mass of copper chloride is 99.0. Hence, formula of copper chloride is

Solution

Correct option is

CuCl

 

Eq. mass of copper chloride = 99

Eq. mass of chlorine = 35.5

       Eq. mass of copper = 99 – 35.5 = 63.5

       Valency of copper 

   Formula of copper chloride is CuCl.
