Describe in detail how you would make one molar solution of sodium chloride.
Do I add the atomic masses of Na and Cl and then find the mols?
And the after that you would just add 1L of water, correct?

Almost.
Yes, you add atomic mass Na to atomic mass Cl. Weigh that amount of NaCl, dissolve it in a litle water, then make to a final volume of 1 L. <b>Note that this is NOT the same as adding 1 L of water. If you weigh 1 mol NaCl and add 1 L water the final volume will be MORE than 1 L. To get the final volume to be 1 L, one must dissolve the NaCl in a little water, then add enough water to make a final volume of 1 L. </b>
