The simplest formula of a compound containing 50% of element X (atomic mass 10) and 50% of element Y (atomic mass 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. wt.","Relative no. of atoms","Ratio"),("X",50,10,50//10=5,2),("Y",50,10,50//20=2.5,1):}`
`therefore` Simplest formula `X_(2)Y`
