The normal freezing point of ethanol,
CH3CH2OH, is -117.30
°C and its Kfp value is 1.99
°C/m. A nonvolatile, nonelectrolyte that dissolves in
ethanol is
chlorophyll.
If 11.74 grams of chlorophyll,
C55H72MgN4O5
(893.5 g/mol), are dissolved in
263.6 grams of ethanol:
The molality of the solution is ??? m.
The freezing point of the solution is ???°C.
