Two elements \( \mathrm{X} \) (Atomic weight \( =75 \) ) and \( \mathrm{Y} \)
P
(Atomic weight \( =16 \) ) combine to give a compound
W
having \( 75.8 \% \) of \( \mathrm{X} \). The empirical formula of compound is :
(A) \( \mathrm{XY} \)
(B) \( \mathrm{X}_{2} \mathrm{Y} \)
(C) \( \mathrm{X}_{2} \mathrm{Y}_{2} \)
(D) \( \mathrm{X}_{2} \mathrm{Y}_{3} \)
