Bоnus: (5 pоints eаch) Yоu mаy аnswer all 3, but Only 1 out of 3 will be graded. Place your final answer in the box or line provided. Show all work for math-based problems to receive credit. No Partial credit for bonus questions. Do not round between steps. Record your final answer to 3 sig figs. Please refer to the Periodic Table handout for the conversion factors needed. Question 1:Calculate the mass of carbon dioxide (g) dissolved in a 4.89L bucket of water exposed to a pressure of 1.46atm in air. The mole fraction of carbon dioxide in air is 0.193 and the Henry’s Law constant for CO2 in water at this temperature is 3.4x10-2 M/atm.Question 2:A solution prepared by dissolving 15.0 g of quinine in 60.0 mL of ethanol has a freezing point 1.98°C below that of pure ethanol. Determine the molar mass of quinine. (The density of ethanol is 0.789 g/mL, Kf=1.99oC/m.) Assume that quinine is a nonelectrolyte.Question 3:A 26.7 g sample of a nonelectrolyte is dissolved in 62.8 g of water. The solution freezes at −4.22 °C. Calculate the molar mass of the substance. (Kbwater = 0.52 oC/m, Tobwater=100oC, Kfwater = 1.86 oC/m, Tofwater=0oC)
