    You have learned that adding table salt, NaCl (58.44 g/mol, 2.16 g/cm3), to water(Kb = 0.52 degrees Celsius/m) increases the temperature at which it boils. You decide to try cooking pasta faster at a higher temperature in boiling salted water. What increase in the boiling point do you expect if you add 1 tablespoon (1 tbsp = 14.8 cm3) of salt to one 8 oz cup of water (237mL)? (assume an ideal van't Hoff factor)
