MCQ

Equivalent weight of a bivalent metal is $37.2$. The molecular weight of its chloride is

A
$412.2$
B
$216$
✓
$145.4$
D
$108.2$

✓

Answer

Correct option: C.

$145.4$

c
(c) Equivalent weight of bivalent metal $= 37.2$

$\therefore $ Atomic weight of metal $ = 37.2 \times 2 = 74.4$

$\therefore $ Formula of chloride $ = MC{l_2}$

Hence, molecular weight of chloride

$(MC{l_2}) = 74.4 + 2 \times 35.5 = 145.4$
