Question 51

Compound $Y\text{Y}$ contains phosphorus and fluorine only, and has a boiling point of $∘C-101.8\ ^\circ\text{C}$ . At room temperature, a $g0.660\text{ g}$ sample of gaseous compound $Y\text{Y}$ is found to occupy a volume of $dm30.180\text{ dm}^3$ . Under these conditions, $mol1\text{ mol}$ of gas molecules has a volume of $dm324.0\text{ dm}^3$ .

Determine the molecular formula of compound $Y\text{Y}$ .
