Answer. Osmotic pressure is the best property to determine the molar mass of biomolecules because it contains concentration in terms of molarity.
Which colligative property is best method?
Osmotic pressure is the best method for the determination of molar mass of proteins and polymers. Because a small amount of solute will produce a much larger change in this quantity than in the boiling point, freezing point, or vapor pressure.
Which is the most important colligative property?
3.1.
Colligative properties include vapor pressure lowering, boiling point elevation, freezing point depression, and membrane osmometry. The latter property is considered here, since it is the most important of the group as far as synthetic polymers are concerned.
Which colligative property is best for molecular mass?
Osmotic pressure is the colligative property used to determine the molecular masses of polymer.
Which colligative property is the best method for determination of molar masses of macromolecules?
Measurement of osmotic pressure method is preferred for the determination of molar masses of macromolecules such as proteins and polymers.
Why osmotic pressure is best colligative property to determination of molar masses?
also in case of polymers since they have very high molar masses they give very less value of the colligative properties which leads to more error but osmotic pressure values are significant enough for higher molar masses.
Which colligative property is the best to determine molecular mass of a polymer and why?
Therefore osmotic pressure is useful to determine the molecular mass of the polymer.
Which colligative property is more useful to determine the molecular weight of the substances like proteins and polymers?
The technique of osmotic pressure for determination of molar mass of solute is particular useful for proteins as they are not stable at high temperature and polymers have poor solubility.
Which of the following colligative properties is most suitable for the determination of molecular masses of proteins and polymers?
Osmotic pressure method is especially suitable for the determination of molecular masses of macromolecules such as protein & polymer because for these substances the value of other colligative properties such as elevation in boililng or depression in freezing point are too small to be measured on the hand osmotic
Which one of the following is not colligative property?
Depression in freezing point is a colligative property but freezing point is not a colligative property.
What are the four types of colligative properties?
There are four colligative properties: vapor pressure lowering, boiling point ele- vation, freezing point depression, and osmotic pressure.
How many types of colligative properties are there?
The four colligative properties that can be exhibited by a solution are: Boiling point elevation. Freezing point depression. Relative lowering of vapour pressure.
Which colligative property uses molarity?
C= Molarity. Was this answer helpful?
Which colligative property can be determined at room temperature?
(ii) osmotic pressure is measured at room temperature.
