Well #6.022xx10^23# atoms of fluorine (as the atom, not as #F_2#) have a mass of #19.00*g#.

Explanation:

And thus #19/(6.022xx10^23*mol^-1)xx19.00*g*mol^-1#

#=# #"not too many grams"#.

We cannot really speak of #0.42*"atoms"# of fluorine. We can have the one atomic particle; we cannot really have 1/2 of an atom.
