Answer: 10ml

In this question, you are given the liquid medicine concentration (100mg/5ml) and the doses of the medicine that must be taken (200mg). You are asked how much ml of the drug needed. Then the calculation would be:

Volume of drug needed = doses of the drug / drug concentration

Volume of drug needed = 200mg / (100mg/5ml) = 10ml
