Assuming ideal behavior, calculate the boiling point in c of solution that contains 64.5g or the non-volatile non-electrolyte quinoline( molar mass= 129g/mole) in 500 grams of benzene. for benzene the normal boling point is 80.10 c and kb = 2.53c/m

Explanation:

The given data is as follows.

     mass of solute = 64.5 g,        mass of solvent = 500 g = 0.5 kg (as 1 kg = 1000 g),  

    Temperature = ,         = 2.53 C/m

Also, we know that the relation between change in temperature, van't Hoff factor(i) and is as follows.

where,    m = molality =

                   =

                   = 1

It is known that for non-electrolyte solute i = 1.

Hence, putting the given values into the above formula as follows.

                        =

                        = 2.53 C

Therefore, calculate the boiling point of the solution as follows.

                    80.10 C + 2.53 C

                  = 82.63 C

Thus, we can conclude that the boiling point of the solution is 82.63 C.

the answer is: they rebelled against saddam hussein’s rule.

kurds opposed saddam rule and wanted independence. kurds in the north and shiites in the south revolt against hussein.

for example, the halabja attack in 1988 conducted against the kurdish people by the iraqi regime under saddam hussein, where between 4000 people are killed and around 9000 are injured.

what are the two models
