Question

If equivalent weight of a trivalent metal is 32.7. The molecular weight of its chloride is :

• A. 32.7
• B. 204.6
• C. 103.7
• D. 68.2

Answer 1

The correct option is B

204.6

Mol. wt. of $MC{l}_3$ = At. wt of $M+3(At.wt.\text{of}Cl)$

$=(E_{Metal}\times \text{valency})+3\left(35.5\right)$

$=(32.7\times 3)+106.5=204.6$
