Question

If the equivalent weight of a trivalent metal is $32.7,$ the molecular weight of its chloride is

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

Answer 1

Answer: (C)

Metal chloride must be $MC{l}_3$

Molecular weight = equivalent weight of metal $\times 3+3$ $\times$ atomic mass of chlorine

$=32.7\times 3+3\times 35.5=204.6$
