5. Often medicine for children is dispensed in a solution form with flavoring added. One such package reads 100 mg acetaminophen in 5.00 mL of liquid. If the doctor prescribes 200 mg of acetaminophen for your toddler, how much of the liquid should be given? Input your answers on Blackboard with the correct number of significant figures. 6. Your infant comes down with the same illness as the child in question 5. The doctor prescribes 60.00 mg of acetaminophen per kg of body weight for the infant who weighs 4.00 kg. Using the same package of acetaminophen as in question 5, how solution should be administered? Input your answers on Blackboard with the correct number of significant much of the figures.
