Simple solution question

Hi all,

I have a very simple problem but for some reason I am having trouble with it.

I need to dope 0.5g of solid powder with element X to a concentration of 500ppm. I have a solution containing 1000ppm element X. How many mL of this solution do I need to add to the 0.5g of powder in order to have it doped at 500ppm?

The liquid part of the solution will dry out in the powder so I am not concerned with it.

Please let me know!
