1a. Medical saline typically consists of 4.50 g of NaCl in 500.0 mL of solution. What is the molarity of this solution? What is the molality of this solution? (Use the density of water = 1 g/mL; for this question, since the concentration is dilute you may assume that the added NaCl does not result in a change in volume when it is added to water.) Do your answers make sense? Would either of these values potentially depend on temperature? 1b. Stomach acid is essentially a solution of hydrochloric acid (HCl).
