Making Solutions

A salt solution has a concentration of 15 g/L. How much of this solution is needed to make 50 ml of a solution which has a concentration of 12 g/L.

Using $$C_1 * V_1= C_2* V_2$$(concentration and volume) I got .4 L of this solution must be added.
I didn't really know how to tackle this one so maybe (if I'm wrong, which I probably am) could someone help me out?

NO,the answer should be 0.04L=40mL.Maybe that's what u've gotten and what u've written is just a typo...

Ya, it wasn't a typo in my post, it was just a silly mistake on paper, but I found it. Thanks dexter.
