There are five compounds in the family of sulfurfluorine compounds with the general formula $\mathrm{S}_{x} \mathrm{F}_{y}$. One of these compounds is $25.23 \%$ S. If you place $0.0955 \mathrm{g}$ of the compound in a $89-\mathrm{mL}$ flask at $45^{\circ} \mathrm{C},$ the pressure of the gas is $83.8 \mathrm{mm} \mathrm{Hg}$. What is the molecular formula of $\mathrm{S}_{x} \mathrm{F}_{y} ?$
