boiling point of water is 100°C
boiling point of soybean oil is 300°
Look up the boiling point elevation constant (K) for the solvent you are using.
The boiling point elevation is the difference in temperature between the boiling point of the pure solvent and that of the solution.
Water has a boiling point elevation constant of 0.512.
Calculate the molal concentration of the solution that will be created after you add your solute to the solvent. For instance, consider a solution created by dissolving 0.5 moles of salt into 1 liter (L) of water. One liter of water has a mass of 1 kilogram (kg), so:
Molality = moles of solute / mass of solvent =
0.5 / 1 = 0.5 m
Boiling point = old boiling point + K x molality
Our water example would look like this:
Boiling point of water = 100 + 0.512 x 0.5 = 100.256 degrees Celsius
boiling point of oil = 300°
But nothing is being added to it so boiling point will be normal

-----------------------------------
1 100°C 300°C
-----------------------------------
2 100°C 300°C
M= 100°C
N= 300°C
300°C - 100°C = 200°C
200°C is the difference
