Actual Molality ( $$\mathrm{m}$$ ) of $$\mathrm{NaCl}$$ solution (use amount of $$\mathrm{NaCl}$$ added): Calculation: Observed Molality ( $$\mathrm{m}$$ ) of $$\mathrm{NaCl}$$ solution (use change in boiling point): Calculation: Mass of sugar $$\left({\mathrm{C}}_{12}{\mathrm{H}}_{22}{\mathrm{O}}_{11}\right)$$ added $$20.\mathrm{Og}/$$ Boiling point of pure $${\mathrm{H}}_2\mathrm{O}$$ /sugar solution observed: Actual Molality ( $$m$$ ) of sugar solution (use amount of sugar added): $$\mathrm{mol}/\mathrm{L}$$ Calculation: Observed Molality (m) of sugar solution (use change in boiling point): Mol/L Calculation: Explain why the boiling points of the solutions are higher than the boiling point of water. (Hint think about vapor pressure.)
