You are studying solubility and saturation by dissolving table
salt (NaCl) in 250 mL of water. You notice that as you increase the
temperature of the water (solvent), you have to add more salt to
stay at the saturation point for the salt. Explain the chemistry
responsible for this observation (i.e., the increasing solubility
of the salt as the temperature of the water is raised).

Twenty-five gram of table salt (NaCl) is dissolved in enough
water to make a solution. How many moles of NaCl are dissolved in
water?
21.4 mole
4.27 × 10-1 mole
42.7 mole
2.14 × 10-1 mole
