A 6% solution of urea is isotonic with
A.Due to association or dissociation of solute✓ Correct
B.Due to insolubility of solute molecules.
C.Due to decomposition of solute molecules.
D.Due to large size of solute molecules.
Explanation
Discrepancies in determination of molar mass arise when the solute dissociate or associate on dissolving in a solvent. This is because due to the association or dissociation of the solute molecules in the solution, the number of molecules undergo a change. SOLUTIONS 50
