Answer:

[tex]V=22.68L[/tex]

Explanation:

Hello,

In this case, we use the ideal gas equation to compute the volume as shown below:

[tex]PV=nRT\\\\V=\frac{nRT}{P}[/tex]

Nonetheless we are given mass, for that reason we must compute the moles of gaseous fluorine (molar mass: 38 g/mol) as shown below:

[tex]n=38 g *\frac{x}{y} \frac{1mol}{38 g} =1mol[/tex]

Thus, we compute the volume with the proper ideal gas constant, R:

[tex]V=\frac{1mol*0.083\frac{bar*L}{mol*K}*273K}{0.999bar} \\\\V=22.68L[/tex]

Best regards.
