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 $
