Acetic acid is found to have molar mass as 120 g mol ^(-1). Prove it.

1.	Acetic acid is found to have molar mass as 120 g mol ^(-1). Prove it.
Answer» SOLUTION :(i) In certain SOLVENT, solute molecules associate to from a dimer. This reduces the total number of molecules formed in solution and as a RESULT the calculated molar mass will be higher than the actual molar mass. (ii) ACETIC ACID in benzene exist as a dimer (iii) The molar mass of acetic acid calculate using colligative properties is found to be around 120 g `mol^(-1)` is two times of the actual molar mass `60 g mol ^(-1)`
