Explanation / Answer

Amount of Dosage per day = 24 mg/six hours * 24 hours/1 day = 96 mg/day

Amount of Dosage per week = 96 mg/day * 7day/week = 672 mg/week

Amount of antihistamine in a tablet = 12.6 mg

Number of Tablets required in a week = Total Dosage in week/ Amount of Dosage in each tablet

=> 672/12.6 = 53.333, hence number of tablets should be 54

Amount of liquid in mL = 672/(12.6/8) = 426.666 = 427 mL
