Answer:
3000mg
Step-by-step explanation:
the dosage as given by the question is 300mg per kilogram per day

∴ 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
