The values of i 



v s for any particular 



solute are fairly 



constant and independent of concentration 



. If we subtract 



the molecular voli 



ime of one amide from 



the next higher 



homologue in the 



series, the difference in volume corres- 



ponding to an addition of 



OH 2 



to the 



molecule can be 



calculated. These results 



are gi 



iven below.
