Dosage question

So...this is somewhat nursing related in that it's a medication dilution, but it's for my plants and I'm a bit stumped.

If I have a tablet that is .03 mg that can be crushed and added to liquid, how do I get a concentration of .003 mg/ml? I add one tablet to 10 ml of liquid, right? Or do I need to count the amount of volume the tablet itself will displace?

0.03mg = 0.003mg

x________1ml

cross multiply

x = 10ml

The amount the pill displaces is very small, so small it would be very difficult to adjust for. Even in my O chem class, we just deal with volume of liquids, we don't consider the displacement of the solid (and our labs are microscale....so we're only dealing with a couple mL's at a time).
