Step 1: Convert weight in pounds to kilograms. 1 kg:2.2 lb = X:66 lb. X = 66 lb/2.2 lb per kg = 30 kg. Step 2: Determine how many milligrams of drug are required. 8 mg/kg F1F1F1S1F1F1F10 30 kg = 240 mg. Step 3: Determine the concentration of the available drug. 2 g/100 ml = 2000 mg/100 ml = 20 mg/ml. Step 4: Determine the dosage volume. 240 mg/X = 20 mg/ml. 240 = 20X; X = 240/20; X =12 ml.
