A saline solution used in intravenous drips for patients who cannot take oral fluids contains 0.92% (w/v)NaCl in water. What volume of the saline solution must be administered to the patient in order to deliver 7.7 g of NaCl?

Question

Quizplus · Accepted Answer

To find the volume of saline solution needed to deliver 7.7 g of NaCl, we use the percentage concentration of the solution. The concentration is 0.92% (w/v), which means 0.92 g of NaCl is present in 100 mL of solution. To deliver 7.7 g of NaCl, we set up a proportion: (0.92 g NaCl / 100 mL solution) = (7.7 g NaCl / x mL solution). Solving for x gives x = (7.7 g * 100 mL) / 0.92 g = 837.0 mL, which is approximately 840 mL.
