QUESTION:
Describe how you would use freezing-point depression and osmotic pressure measurements to determine the molar mass of a compound. Why are boiling-point elevation and vapor-pressure lowering normally not used for this purpose?
ANSWER:Step 1 of 2
Vapor pressure lowering and boiling point elevation are usually not used because they exhibit fewer obvious changes and are therefore inaccurate.
Boiling point elevation is less susceptible than freezing point depression to the number of moles of the solute because for equivalent solvent is larger than
