A) 1 : 2 : 3
B) 1 : 3 : 2
C) 2:3: 1
D) 3:2:2
Correct Answer: B
Solution :
Molar ratio of X, Y and \[Z=\frac{4.2}{7}:\frac{5.4}{27}:\frac{19.2}{64}\] \[=0.\text{6}:0.\text{2}:0.\text{3}=\text{6}:\text{2}:\text{3}\] As atomic weight = Equivalent weight x valence Y and number of equivalents is same in all three. Therefore, valency ratio of X, Y and Z is 1: 3 : 2.You need to login to perform this action.
