Here, we want to state why dosages of medicine are not presecribed as moles or molecules
The reason for this is because while it is possible to measure the dosage since it is directly based on mass, it might be quite difficult to measure moles or molecules.
For example it might be impossible to count the number of molecules.
Thus, beacuse mass is a fundamental quantity on which the dosages are based, it is quite very easy to prescribe in terms of dosages.
