For these molarity problems, just remember the definition.
Molarity = # mols/Liter of solution.
So convert grams NaCl to moles (# moles = g/molar mass) and divide by the number of liters. Voila!

I assume the molmass of NaCl is about 58
Molarity=mass/(molmass*literssolution)

NO. do the calculation. You wouldn't want to get the reputation of being an answer moocher.
