You just need to balance the equation, which is the art of stoichiometry.

Na+Cl2=NaCl

Balance this by adding a 2 in front of Na and NaCl

2Na+Cl2=2NaCl

Now they are equal.

However your question asks that there be 5 moles of sodium, we balanced 2.

Since they are equal, you just multiply 2 by a number that makes everything 5.

It will be 2.5 in this case.

5Na+2.5Cl2=5NaCl

You need 2.5 moles of Cl2.
