The doctor has to give 12 ml for 3 g of medication at a 25mg/ml ratio to the patient.
Here the doctor is giving 3 g of medication to the patient.
The concentration ratio for the medication is 25mg/ml.
Medication is given to the patient= (Amount medication)/(Concentration Ratio)
= 3/ 0.25
= 12 ml
Thus the amount to be given to the patient is 12ml with a 25mg/ ml concentration ratio.

<u>Experimental studies</u>
<u>Experimental studiesIn an experimental study, the investigator determines through a controlled process the exposure for each individual (clinical trial) or community (community trial), and then tracks the individuals or communities over time to detect the effects of the exposure. For example, in a clinical trial of a new vaccine, the investigator may randomly assign some of the participants to receive the new vaccine, while others receive a placebo shot. The investigator then tracks all participants, observes who gets the disease that the new vaccine is intended to prevent, and compares the two groups (new vaccine vs. placebo) to see whether the vaccine group has a lower rate of disease.
