Boiling point elevation 3

Chemistry Level pending

Pure toluene has a normal boiling point of 110.60 110.60 °C. A solution of 3.90 3.90 g of anthracene(C 14 _{14} H 10 _{10} ) in 50.0 50.0 g of toluene has a boiling point of 112.16 112.16 °C. Calculate the boiling point evaluation constant K b K_b for toluene.

3.56 K kg mol − 1 3.56\text{ K kg mol}^{-1} 2.31 K kg mol − 1 2.31\text{ K kg mol}^{-1} 1.67 K kg mol − 1 1.67\text{ K kg mol}^{-1} 4.62 K kg mol − 1 4.62\text{ K kg mol}^{-1}
