A compound contains two elements ‘x’ and ‘y’ in the ratio of 50% each. Atomic mass of ‘x’ is 20 and ‘y’ is 40. What can be its simplest formula?
A
XY
B
X2Y
C
XY2
D
X2Y3
Answer
X2Y
Explanation
Solution
(2) : Percentage of element‘X’= 50,
Mole ratio =2050=2.5
Percetange of element ‘Y’ = 50,
mole ratio = 4050=1.25
For ‘X’ simple ratio= 2.5/1.25=2
For ‘Y’ simple ratio = 1.25/1.25=1
Formula =X2Y
