Find the number of moles of particles for NaCl

2 answers

I have no idea what you mean

there are about 6*10^23 anythings per mole just like there are 12 anythings per dozen
You need a mass of NaCl.
Then mols NaCl = grams/molar mass = ?
Finally, mols Na^+ = mols NaCl x 6.02E23
mols Cl^- = mols NaCl x 6.02E23
# particles will be the sum of #Na^+ + #Cl^-
