The molecular weight of non-volatile solute can be determined experimentally by osmotic pressure method or by cryoscopy or by ebullisocopy Berkeley-Hartley method for isotomic presure is commonly used for aqueous solutions. Elevation in `b.pt.` or depression in `f.pt.` on addition of non-valatile solute in a solvent is read by Beckmann's thermometer.
