People commonly dissolve table salt (NaCL) into water that they are heating up. a) If you had a pot with 4 quarts of water (before heating) and add 1 teaspoon of salt, which is equivalent to 6.20g, what is the boiling point of the water? How much of an effect will that have on cooking pasta? (You can assume that NaCl fully dissociates. 1quart=0.946 L and Kb=0.51oCkg/mol for water) b) Would the cooking of pasta (based on boiling point) be...
