Problem: In making a large vat of coffee, how much would the boiling point (in °C) of the water be raised by the addition of 0.2 grams of caffeine, (C8H10N4O2 a polar covalent molecule) to 5.0 L of water in making this much coffee? Ignore all the other ingredients of the coffee (except the water and the caffeine) and assume that the final amount of coffee make is 10.0 L. (Kb for water is 0.512 K kg mol-1). a. 0.0001 b. 0.05 c. 0.00005 d. 0.001 e. 0.0005
