What is the boiling point of an benzene solution that freezes at 0.3 degrees c? normal freezing point is 5.5 and the normal boiling point is 80.1 degrees c. kfp = 5.12 k/m and kbp = 2.53 k/m. enter your answer to 2 decimal places.

The boiling point of an benzene solution is

Explanation:

Depression in freezing point is given by:

= Depression in freezing point

i= vant hoff factor = 1 (for non electrolyte)

= freezing point constant =

m= molality

Elevation in boiling point is given by:

= elevation in boiling point

i= vant hoff factor = 1 (for non electrolyte)

= boiling point constant =

m= molality = 1.015

Thus the boiling point of an benzene solution is

fgravity=10x10=100n case 1

fgravity=30x20=600n case 2

the answer is b, have negligible mass
