"Molarity" = ("Moles of solute")/("Volume of SOLUTION").

And we get an answer with units, mol*L^-1

Explanation:

So all we need to do is to set up this quotient. You have been given the amount of solute in moles, and the volume of solution.

So, "Molarity" = (3*mol)/(4*L) = ?? mol*L^-1?

In 1 L of this solution, what is the mass of the NaCl solute?
