How many moles of sodium ions are there in 5.85g NaCl?

Question

So far all I have tried to do is 5.85/58.5=0.1 mol of NaCl but I don't understand how you find the number of moles of sodium ions only.

Answer 1

You have 0.1 mol NaCl. That's correct.
So there is 1 mol Na/1 mol NaCl and 1 mol Cl/1 mol NaCl. Right?
