How is molecular mass of a solute related to the elevation in boiling point of the solution?

Assertion : Molecular mass of polymers cannot be calculated using boiling point or freezing point method. Reason : Polymer solutions do not possess a constant boiling point or freezing point. 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.

Show graphically how the vapour pressure of a solvent and a solution of a non volatile solute change with temperature. Show the boiling points of the solvent and the solution in the graph. Which is higher and why?

Solution exhibit certain colligative properties such as elevation in boiling point, depression in freezing point , osmotic pressure. 10g of an organic substance is dissolved in two litres of water at 280 K. Find out the molar mass of the substance if osmotic pressure of the solution id 0.6 atmospheres

The boiling point of a pure liquid is 353.23 K. When 1.80 g of a non-volatile solute is dissolved in 90 g of this pure liquid, the boiling point becomes 354.11 K. The molar mass of the solute is (given that the boiling point elevation constant function of the pure liquid is 2.53 K. kg. mol^-1 )

solution exhibit certain colligative properties such as elevation in boiling point, depression in freezing point , osmotic pressure. Cold ethylene glycol is added to radiator in vehicles. Which colligates property of water is involved in doing this ? Explain.

An aqueous solution of '2 %' non-volatile sol ute exerts a pressure of 1.004 bar at the nor mal boiling point of the solvent. What is the molar mass of the solute?
