Question

What is the molarity of a sodium chloride solution that contains 3 moles of `NaCl` in 4 liters of solution?

Answer 1

`"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?
