Dosage

A dosage is the amount of a medicine or drug that someone takes or should take, and how ` they should take it.

1 oz = 0.0283495 kg; also 1 lb = 0.453592 kg.

Hence 15 lb 6 oz = (15 lb * 0.453592 kg/lb) + (6 oz * 0.0283495 kg/oz) = 6.97 kg

Since the dosage is 50 mg/kg/day. Hence amount of mg given is:

Amount of mg = 50 mg/kg/day * 6.97 kg = 348.5 mg per day

Each 10 ml contains 400 mg; hence:

ml = 348.5 mg * 10 ml per 400 mg = 8.71 ml per day

Thomas should receive 8.71 ml per day
