Calculate the boiling point (in degrees C) of a solution made by dissolving 3.59 g of anthracene (C14H10) in 88.5 g of CCl4. The Kbp of the solvent is 4.95 K/m and the normal boiling point is 76.5 degrees C. (value ±0.1 ºC)
What is the boiling point of a solution that contains 15.9 grams of CCl4 dissolved in 157 grams of ethanol (C2H6O)? For pure ethanol: boiling point = 78.4 °C freezing point = -114.6 °C Kb = 1.22 °C/m Kf = 1.99 °C/m Molar masses: CCl4 = 153.81 g/mol ethanol = 46.08 g/mol
