Suppose the boiling point of a solution of 1.15 g of an unknown molecular substance in 8.51 g of the solvent benzene is measured to be 58.5°C. The boil point of pure benzene is 55.0°C. The molal
boiling point elevation constant for benzene is 2.53 °C kg/mol. What is the change in boiling point
for the solution?
A) 58.5°C
B) 55.0°C
C) 3.5°C
D) - 3.5°C
