Question

Calculate the boiling point elevation of a solution containing 22.8 g of glucose (C6H12O6) dissolved in 672.0 g of water. Calculate the freezing point depression for the same solution.

Answer 1

delta T = Kb*molality
molality = moles/kg solvent
moles = g/molar mass
[convert 22.8 g glucose to moles using equation 3. Convert moles glucose to molality using equation 2. Then calculate delta T using equation 1.]


Then delta T = Kf*m
for the freezing point section. The same moles and molality may be used in this part.
