A compound contains elements

\text{X}

and

\text{Y}

1: 4

mass ratio. If the atomic masses of

\mathrm{X}

and

\mathrm{Y}

are in

1: 2

ratio, the empirical formula of the compound should be

View answer and explanation

Correct option: A

\mathrm{XY}_2

Option A (

\mathrm{XY}_2

) is correct because the empirical formula is determined by the simplest whole number ratio of the elements, calculated from their mass ratio and atomic mass ratio.
