Most likely in between both pure substance Bp.'s, this cannot be calculated, it has to be experimentally measured and determinated (Tx,y diagram)
Ethanediol: Bp. 197.3 °C (470 K)
Ethanol: Bp. 78.4 °C, 352 K

What is the boiling point of a solution of 1250 g of c6h12o6 in 350 g c2h5oh kb for c2h5oh is 119cm and the boiling point of c2h5oh is 78c?
35 c
Why must you let a solution evaporate at room temperature in order to get a salt?
The solution does not have to be at room temperature. Depending on what the solution is, the solution must be heated to it's proper boiling point in order for it to evaporate. Everything has a melting, freezing and a boiling point, and the salt's melting and boiling point's are extremely high, therefore the salt will be left behind when the solution is evaporated, unless the solutions boiling point is higher then the salt's boiling point.
What lowers the freezing point and raises the boiling point?
Yes, it is possible if the solution contain solutes.
What happpens to the boiling point of a solution?
At the boiling point liquids become gases and if the solution contain dissolved solids they remain as residues.
Is alcohol solution boiling point higher or lower than salt solution?
Lower. The boiling point of ethanol is 78 degrees C. Adding salt to water raises the boiling point of that solution above 100 degrees C.

Why c2h5oh has higher boiling point?
due to intermolecular hydrogen bonding
Ethanol c2h5oh and methyl ether ch3och3 have the same molar mass.W hich has a higher boiling point?
ethanol has a higher boiling point- of 78°C :)
The boiling point of a liquid solution is?
Higher then the boiling point of the solvent.
The difference between the boiling point of a liquid in pure state and the boiling point of the liquid in solution?
Boiling Point Elevation
Ethanol has a heat of vaporization of 38.56 kj per mol and a normal boiling point of 78.4 degrees Celsius - What is the vapor pressure of ethanol at 18 degrees Celsius?
We are considering the process: C2H5OH (l) -> C2H5OH (g) Kp = P(C2H5OH) At the normal boiling point of C2H5OH, the equilibrium constant, Kp, for this process is 1, and ΔG0 = -RTln(K) = 0 = ΔH0 - TΔS0. Substituting 42600 J for ΔH0 and 78.5 + 273.15 = 351.65 K for T gives ΔS0 = 121 J/K.
