A sample of sulfur weighing 0.210 g was dissolved in 17.8 g of carbon disulfide, CS2 ( Kb=2.43 C/m). If the boiling point elevation was 0.107 C, what is the formula of a sulfur molecule in carbon disulfide?
A solution of benzoic acid in benzene has a freezing point of 3.1 C and a boiling point of 82.6 C. (The freezing point of pure benzene is 5.50 C, and its boiling point is 80.1 C) The structure of benzoic acid is Benzoic acid, C6H5CO2H What can you conclude about the state of the benzoic acid molecules at the two different temperatures?

8.51 Suppose that three unknown pure substances are liquids at room temperature. You determine that the boiling point of substance A is 53°C, that of substance B is 117°C, and that of substance C is 77°C. Based on this information, rank the three substances in order of their vapor pressures at room temperature.
Consider the following formulas for n-pentane and neopentane: CH3CH2CH2CH2CH3 -Pentane Both compounds have the same overall formula (C5H12, molar mass = 72.15 g/mol), yet n-pentane boils at 36.2C whereas neopentane boils at 9.5C. Rationalize the differences in the boiling points between these two nonpolar compounds.
