Some Basic Concepts Of Chemistry Question 120

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

Options:

A) 412.2

B) 216

C) 145.4

D) 108.2

Show Answer

Answer:

Correct Answer: C

Solution:

[c] Equivalent weight of bivalent metal = 37.2

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

$ \therefore $ Formula of chloride $ =MCl _2 $ Hence, molecular weight of chloride $ (MCl _2)=74.4+2\times 35.5=145.4 $
