What is the boiling point of a 3 molal aqueous solution if Kb is 0.512°C/m?
A solution was made by dissolving 2 g of a solute in 100 g of acetone. The solution boiled at 56.95° C. The boiling point of pure acetone is 55.95° C, and the Kb =1.71°C/m. What is the molecular weight of the solute?
The molal elevation constant is the ratio of the elevation in B.P to:
Which of the two has lower freezing point, 2m NaCl or 5m NaCl aqueous solution?
If the vapour pressure of pure solvent A is 17.5 mm and lowering of vapour pressure of solution formed by adding a non-volatile electrolyte is 0.0175 mm then what is the relative lowering of vapour pressure?
Which of the following unit of concentration is independent of temperature?
Relative lowering of vapour pressure is directly proportional to
