A compound contains 50% of X (atomic mass 10) and 50% Y (atomic mass 20). Give its empirical formula.

Text Solution

Verified by Experts


`therefore`The Empirical Formula is `X_(2)Y`
Empirical Formula mass=20+20=40
`n=1,therefore` Molecular formula=`("Empirical Formula")_(n)=(X_(2)Y)_(1)=X_(2)Y`.
