Combine 4 and 1/6 mL of the 12 M solution with 495 and 5/6 mL of water.

Practically this is right; technically it is not.
Technically, the volumes are not additive; therefore, what you do is pipet 4 and 1/6 mL of the 12 M into a 500 mL volumetric flask and add enough water to make exactly 500 (fill to the mark of the flask). That way you KNOW you have a final volume of 500 mL.

That's the same thing. You just measure the water with the first solution. :/
