Calculate equivalent weight of `Cu` in `CuO` and `Cu_(2)O`. At.wt. of `Cu=63.6`.

What is the valency of Cu in CuO and Cu_2O ?

Calculate the equivalent weights of zinc and zinc sulphate (At.wt. of Zn = 65.4).

Calculate the percentage of Cu in CuO

(A) : Equivalent weight of Cu in CuO is 63.6 and in Cu_(2)O is 31.8. (R) : Equivalent weight of an element =("Atomic weight of an element")/("Valency of the element")

The equivalent weight of iron in ferric chloride is ( At.wt. of Fe = 55.8) -

When Cu_(2)S is converted into Cu^(2+) & SO_(2) then equivalent weight of Cu_(2)S will be (M=mol. Wt. of Cu_(2)S )

When Cu_(2)S is converted into Cu^(2+) & SO_(2) then equivalent weight of Cu_(2)S will be (M=mol. Wt. of Cu_(2)S )
