Hello, Gabby,
I'm not certain what the question is tying to ask, but this is my reaction (so to speak):
1 mole is Avogadro's number of particles, which is 6.02x10^23. That means 1 mole = 6.02x10^23 particles, or the other way around: 6.02x10^23 particles = 1 mole.
If written as a conversion factor, it can be stated as either
1mole/(6.02x10^23 particles), or
(6.02x10^23 particles)/mole
They are conversion factors, since each is equal to "1." You can use them to multiply any result, since 1 x Thing = Thing. Their use is to change the units:
Given that you have 5 moles of NaCl, I can convert that value into particles:
5 moles x (6.02x10^23 particles)/mole = 3.01x10^24 particles.
I'm not clear if this is what the question is asking, but these answers would make sense.
Bob
