You were asked to administer a particular medication to a patient. The medication bottle is labeled to contain 25 mg/mL of active ingredient. If you want the patient to receive 0.0125 g of the medication, how many milliliters (mL) will you need to draw up the syringe?

IV (intravenous) solutions are mixtures of sugars, salts and other aqueous solutes fed directly to a patient's veins. If an IV solution is 5.0% glucose by mass, how many grams of solid glucose would be require to prepare 60.0 milliliters (ml) of the solution? Assume the density of the solution is 1.0 g/ml
