The simplest formula of a compound containing 50% of an element `X` (atomic weight 10) and 50% of element `Y` (atomic weight 20) is:

A

`XY`

B

`X_(2)Y`

C

`XY_(3)`

D

`X_(2)Y_(3)`

Text Solution

Verified by Experts

The correct Answer is:
B
`{:("Element",%,"At. mass","% At.mass","Atomic ratio"),(X,50%,10,(50)/(10)=5,2),(Y,50%,20,(50)/(20)=2.5,1):}`
`:.` Formula `=X_(2)Y`
