A compound contains two elements 'X' and 'Y' in the ratio of 50% each. Atomic mass 'X' is 20 and 'Y' is 40. what can be its simplest formula?

A

XY

B

`X_2Y`

C

`XY_2`

D

`X_2Y_3`

Text Solution

Verified by Experts

The correct Answer is:
B
Percentage of element 'X' = 50
Mole ratio `=50/20=2.5`
Percentage of element 'Y' = 50, mole ratio `=50/40=1.25`
For 'X' simple ratio = 2.5/1.25=2
For 'Y' simple ratio = 1.25/1.25=1
Formula `=X_2Y`
