M B (abnormal) > M B (normal) when i < 1. In case of association, Van’t Hoff factor is less than 1, therefore, Naturally, this molar mass is larger than the normal formula molar mass. Acetic anhydride (CH3CO)2O or C4H6O - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more. Now in this case the molar mass of the solute is equal to the mass of 6.023 x 10 23 units of formula (CH 3COOH) 2. While in solution the solution dimerises and becomes a bigger molecule like (CH 3COOH) 2. In case of a normal solute like CH 3COOH, the molar mass of acetic acid is equal to the mass of 6.023 x 10 23 molecules of formula CH 3COOH. But we know that the molar mass is defined as the mass of 6.023 x 10 23 particles of the substance. The molar mass of acetic acid in a solution of benzene solvent is greater than its formula molar mass because two CH 3COOH molecules form a dimer (CH 3COOH) 2 in solution. If Kf K f for water is 1.86C/m 1.86 C / m, the freezing point of. A 0.1 molal aqueous solution of a weak acid is 30 ionized. The molar mass of protein will be ( R0.083Lbarmol1K1 R 0.083 L b a r m o l 1 K 1 ): Answer. Since the eletrolytes ionise and give more than one particle per formula unit in solution the colligative effect of an eletrolyte solution is alaways greater than that of a non electrolyte of the same molar concentration. The Osmotic pressure of this solution at 300K 300 K is found to be 2.57×103 2.57 × 10 3 bar. The colligative properties of solution depend on the total number of solution. Acetic anhydride (CH3CO)2O or C4H6O - structure, chemical names, physical and chemical properties, classification, patents, literature, biological activities, safety/hazards/toxicity information, supplier lists, and more.
