Question: 5mg is how many cc?
Answer: Since you want 10 mg and 5 mg, you want 0.010 and 0.005 ccs. These are very small quantities! Are you sure you don't mean that you need 10 ml or 5 ml not 10 mg or 5 mg? If it says "ml" (or "mL") then that means the same as cc, so it is asking for 10 cc or 5 cc, which your dropper can dispense.
