A patient weighs 164 pounds (1.000 pound = 0.454 kg). The patient requires a dose of a drug that is 4.50 mg/kg of body weight. You have a stock solution of the drug that is at a concentration of 60,000 ppm. The density of the stock solution is 1.16 g/mL. The drug has a molecular mass of 623.87 g/mol. You decide to give the patient the drug using an i.v. bag (intravenious injection) with a volume of 1.00 L and pump it into the patient at a rate of 10.0 ml/min. What volume of the stock solution of the drug do you need to add to the i.v. bag in order to ensure that the patient gets the correct dose?
