The boiling point elevationof an aqueous sucrose solution is found to be 0.39 degrees Celsius. What mass of sucrose (molar mass=342.30g/mol) is contained in 500g of the solution? Kb (water)=0.512degrees C/m

  • Chemistry - ,

    delta T = Kb*molality
    Solve for m

    m = moles solute/kg solvent
    Before going further, are you sure you have copied the problem correctly? There is a difference between 500 g SOLUTION and 500 g SOLVENT.

  • Chemistry - ,

    Also, if it is 500 g solution, a density is needed.
