8) _______ A) 8.32 °C B) -8.32 °C C) 70.2 °C D) 30.0 °C E) -30.0 °C 9) Calculate the boiling point of a solution of 500.0 g of ethylene glycol (C 2 H 6 O 2 ) dissolved in 500.0 g of water. K f = 1.86 °C m - 1 and K b = 0.512 °C m - 1 . Use 100 °C as the boiling point of water. 9) _______ 10) A compound is found to have a molar mass of 598 g mol - 1 . If 35.8 mg of the compound is dissolved in enough water to make 175 mL of solution at 25 °C, what is the osmotic pressure of the resulting solution? 10) ______ 11) A 150.0 mL sample of an aqueous solution at 25 °C contains 15.2 mg of an unknown nonelectrolyte compound. If the solution has an osmotic pressure of 8.44 Torr, what is the molar mass of the unknown compound? 11) ______ 12) Calculate the total solution volume required to produce an osmotic pressure of 4.87 mbar using 8.21 mg of a protein with a molar mass of 4450 g mol - 1 at 25.0 °C. 12) ______ A) 8.00 mL B) 10.6 mL C) 9.39 mL D) 12.3 mL E) 4.79 mL 13) Calculate the solution temperature required to produce an osmotic pressure of 1.10 mbar using 3.85 mg of a protein with a molar mass of 4183 g mol - 1 that is dissolved in enough water to create 20.0 mL of solution. 13) ______ 1) E 2) D 3) C 4) D 5) A 6) D 7) D 8) E 9) B 10) A 11) E 12) C 13) C #### You've reached the end of your free preview.
