What is the molarity of a solution that contains 125 g NaCl in 4.00 L solution?

a.8. 56 M

b.31.3 M

c. 2.14 M

d/ 0.535 M

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)
