Consider a system that consists of water and sodium chloride (NaCl) at room temperature and atmospheric pressure. The student is asked to determine the minimum amount of NaCl that needs to dissolve in 100 grams of water in order to form a saturated solution. The student should also calculate the molar solubility of NaCl in the solution.
