It is vital to weigh the amount of powder that you want to volumetrically dose with a [[Dosage#Milligram scale|milligram scale]]first. Even if the weight is on the bag itself, do not assume that the vendor has given you a certain amount of a substance; it is not uncommon for vendors to give more product than is labelled. If one believes they received 500mg, but actually received 1000mg, then the liquid solution will be twice as strong as expected.

To achieve a concentration of 10mg/1ml, measure the weight of material in milligrams, then divide the value by 10. So for 1000mg material, 100ml of solvent will be required. It is safest to use the lowest concentration possible, preferably 1mg/1mL or less for very potent drugs active in the 1mg range.
