200 ml of 4% solution contains 400 mg of medication
Explanation:
- 0.5 ml of solution has 1 mg of medication
- for example, if 10 mg of medication needs to be determined all we must do is multiply 0.5 ml of solution by 10 mg of medicine to get the answer.
- in the above question we need to determine the number of milliliters of a 4% solution containing 400 mg of medication.
- all we must do is multiply 0.5 ml of solution to 400 mg of medication to get the answer.
0.5 ml x 400 mg = 200 ml
