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

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.

Relative lowering of vapour pressure, elevation of boiling point, depression of freezing point and osmotic pressure are important colligative properties of dilute solutions. Relative lowering of vapour pressure of an aqueous dilute solution of glucose is 0.018 What is the mole fraction of glucose in the solution ?

Among the following which is not a colligative property ? a) Osmotic pressure b) Elevation of boiling point c) Vapour of boiling point d) Depression in freezing point

A solute of weight.‘W’ g is dissolved ‘V’ litres of water at T temperature.If ‘P’.is the osmotic pressure, calculate the molecular weight of solute ?

Show that (i) elevation in boiling point is a colligative property (ii) depression in freezing point is a colligative property and (iii) osmotic pressure is a colligative property?

The osmotic pressure of a solution containing 0.10g of haemoglobin in 10 cm of solution is 30 Torr at 300 K. The molar mass of haemoglobin is nearly

.ietermine the osmotic pressure of a solution prepared by dissolving '25 mg' of 'K_2S O_4' in 2 litre of water at '25^circ' C assuming that it is completely dissociated.

The boiling point of benzene is 353.23K. When 1.80g of a non-volatile solute was dissolved in 90g of benzene, the boiling point is raised to 354.11K. Calculated the molar mass of the solute k_b for benzene is 2.53K kg mol^(-1)

0.48g of a substance was dissolved in 10.6 g C_6H_6. The freezing point of benzene was lowered by 1.8^@C. Calculate molar mass of the substance. Molecular depression constant for benzene is "5K kg mol"^(-1) .
