Colligative properties, are used to determine _______

Which instrument is used to accurate determination of atomic masses.

Colligative properties can be used to determine the molecular mass of solutes in solutions. For determining the molecular mass of polymers, osmotic pressure is preffered to other properties. Why ?

Which of the following colligative properties can provide molar mass of proteins (or polymers or colloids with great precision)

Assertion : Molecular mass of KCl calculated on the basis of colligative properties will be lower than the normal molecular mass. Reason : Experimentally determined molar mass is always lower than the true value. a)If both (A) and (R) are correct and (R) is the correct explanation of(A). b)If both (A) and (R) are correct, but (R) is not the correct explanation of (A). c)If (A) is correct, but (R) is incorrect. d)If both (A) and (R) are incorrect.
