What is the # of atoms in 6PCI5

i have science homework and i can't find the answer to this problem.
Calculate the # of atoms in 6PCI5.
I HAVE NO IDEA!!!!!!!!!!

6PCl5 has 6 Phosphorus Atoms and 5 Chlorine Atoms in its formation = 11 Atoms in total.

6 PCl5 has 36 moles of atoms x 6.022x10^23 = 2.15x10^25 atoms

yikes. each PCl5 has 6 atoms 1P and 5 Cl
and you have 6PCl5; thus you have 6*6=36 atoms
