Question

The equivalent weight of a divalent metal is $W$. The molecular weight of its chloride

• A. $W+35.5$
• B. $2W+35.5$
• C. $W+71$
• D. $2W+71$

Answer 1

The correct option is D $2W+71$

The equivalent weight of the divalent metal is $W$
Molar mass of the metal will be $2W$
Formula of the metal chloride $=MC{l}_2$
Molecular weight of the compound $=2W+(2\times 35.5)$
Molecular weight $=(2W+71)$
