The answer is #"5.56 mol PCl"_3"#.

Explanation:

One mole of molecules is #6.022xx10^23# molecules.

Divide the number of molecules of #"PCl"_3"# by #(6.022xx10^23"molecules")/"mol"# by multiplying by its inverse.

#3.35xx10^24"molecules PCl"_3xx(1"mol PCl"_3)/(6.022xx10^23"molecules PCl"_3)="5.56 mol PCl"_3"# rounded to three sig figs
