Question

The equivalent weight of bivalent metal is $32.7g/eq$. The molecular weight of its chloride is:

• A. $68.2$
• B. $103.7$
• C. $136.4$
• D. $166.3$

Answer 1

The correct option is C $136.4$

Atomic weight of bivalent metal = $equivalentweight\times valency=32.7\times 2=65.4$.

For a bivalent metal, formula for its chloride = ${MCl}_2$

Since, atomic weight for $Cl$ = 35.5

So, molecular weight = 65.4 + 2(35.5) = 136.4
