Answer:

#4xx1.4xxN_A#, where #N_A ="Avogadro's Number"#

Explanation:

#N_A ="Avogadro's Number"# #=# #6.02214xx10^23#. #1# #mol# of stuff contains this many particles of stuff.

Since there are 4 atomic particles in #PF_3#, #1.4# is multiplied by #4#, and then by #N_A# to give the total number of atoms/particles.

So, how many phosphorus atoms in #1.4# #mol# #PF_3#; how many fluorine atoms?
