Dilution problem question

Question

Question: There are only 37.5 mL left of the 6.0M NaOH stock solution. A lab calls for 0.75M NaOH solution. What volume of the solution can be made?

I've tried converting the mL into liters and then moles, but i'm not sure if i'm on the right track.

Answer 1

No need to convert to liter, and moles do not enter into the equation. This is a simple dilution problem where you can use M1V1= M2V2

(6.0 M)(37.5 ml) = (0.75 M)(x ml)

x = 300 mls of the final solution can be made.

You would dilute the original 37.5 ml up to a final volume of 300 ml.
