Normal saline solution used in IVs is usually around 0.90% m/v or 0.154 M; however, other saline solutions may have a higher or lower concentration of sodium chloride, NaCl, depending on the use. For example, a hypertonic saline solution with a concentration greater than 0.154 M may be used to treat hyponatremia (sodium concentration in the serum is too low). Calculate the molarity of the NaCl solution when 43.8 g of NaCl is dissolved in 100 mL of water. Express the molarity with the appropriate units. • View Available Hint(s) HA Value Units Submit
