X and Y are two different elements having their atomic masses in 1:2 ratio. The compound formed by the combination of X and Y contains 50% of X by weight. The empirical formula of the compound is

Options

A. `X_(2)Y`
B. `XY_(2)`
C. `XY`
D. `X_(4)Y`

Answer

A

Explanation

`W%` of `x = 50`,
`W%` of `y = 50`
`AW` of `x = 1`,
`AW` of `y = 2`
`{:("atomic ratio","simple ratio",E.F),((50)/(1)=50,(50)/(25)=2,X_(2)Y),((50)/(2)=25,(25)/(25)=1,):}`
