A) 17
B) 21
C) 25
D) 27
Correct Answer: D
Solution :
By using: Valency of an element \[=\frac{Approximate\text{ }weight}{Equivalent\text{ }weight}\] \[=\frac{26.8/specific\text{ }heat}{Equivalent\text{ }weight}\] \[=\frac{26.8/1.05}{9}=2.835=3\] Now, by using Atomic weight = Equivalent weight\[\times \]valency \[=9\times 3=27\]You need to login to perform this action.
