Approx. 5*mol.................

Explanation:

The molar volume of an Ideal Gas at "STP" is 22.4*L, and thus number of moles ="volume of gas"/"molar volume". We assume that behaviour of F_2(g) approaches ideality.

=(115.6*cancelL)/(22.4*cancelL*mol^-1)=5.16*1/(mol^-1)

=5.16*1/(1/(mol))=5.16*mol.

What is the mass of this quantity of gas?
