You have a stock solution of 15.0 M NH3 . How many milliliters of this solution should you dilute to make 1200ml of 0.280 M NH3?

If you take a 15.0ml- portion of the stock solution and dilute it to a total volume of 0.600 L , what will be the concentration of the final solution?

This is a two part question thanks!
