Answer:

#"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?
