Answer:

3000mg

Step-by-step explanation:

the dosage as given by the question is 300mg per kilogram per day

this implies that for a unit kg and and a unit day 300mg should be administered

∴ for a child of 30kg

amount to be administered per day = 30 × 300 = 9000mg

one day = 24 hours

∴ amount to be administered per hour = 9000÷24 = 375mg

therefore amount to be given every 8hours = 375 × 8 = 3000mg
