You MUST know that elemental fluorine is the gaseous #F_2# molecule.

Explanation:

And in fact all the elemental gases, save for the Noble Gases, are bimolecular species. Is this true?

And we use the Ideal Gas Equation:

#PV=nRT="mass"/"molar mass"xxRT#

And thus #"mass"=(PVxx"molar mass")/(RT)#

And we plugs in the numbers:

#(1.54*atmxx3.2*Lxx38.0*g*mol^-1)/(0.0821*(L*atm)/(K*mol)xx313.1*K)=#

#7.29*g#.

Remember what I said with regard to the so-called molecularity of elemental gases. And fluorine gas, the most reactive substance on the Periodic Table, is not to be handled without special precautions.
