We’re gift asked todetermine the boiling allude of a solution. The solution is composed of6.4 g vanillinin50.0 g ethanol.
You are watching: The boiling point of ethanol is 78.5
Recall the theboiling point of a solutionishigherthan that of the pure solventand thechange in boiling point (ΔTb)is offered by:
Thechange in boiling pointis alsorelated to the molality the the solution:
i= van’t Hoff factor
m= molality that the equipment (in m or mol/kg)
Kb= boiling suggest elevation constant (in ˚C/m)
Recall the themolality that a solutionis provided by:
The boiling allude of ethanol (C2H5OH) is 78.5°C. What is the boiling suggest of a solution of 6.4 g of vanillin (ℳ = 152.14 g/mol) in 50.0 g of ethanol (Kb that ethanol = 1.22°C/m)?
