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 ?

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 vapour pressure of pure liquid A is 10 torr and at the same temperature , when 1 g, of B is dissolved in 20 g of A, its vapour pressure reduced by 1 torr. If the mol wt.of A is 200 u, then the molecular weight of B is

A certain volume of Ar gas require 45 sec to effuse through a hole at a certain pressure and temperature. The same volume of another gas of unknown molecular weight require 60 sec to pass through the same hole under the same condition of temperature and pressure. The molecular weight of gas is

Determine the amount of 'CaCl_2(i=2.47)' dissolved in 2.5 litre of water such that its osmotic pressure is '0.75 atm' at '27^circ C'

When the same amount of the solute 'p' and 'Q' are separately dissolved in 500g water, the Delta T_(f) values are 0.15K and 0.30K respectively. If the molecular weight of 'P' is 80" g mol"^(-1) , then the molecular weight of 'Q' is

A given solution of NaOH contains 2.00 g of NaOH per litre of solution. Calculate the molarity of this solution?

The osmotic pressure of a non-electrolytic solution is '500 mm Hg' at '10 C .' The solution is diluted and its temperature is raised to '30C'. It is now found that the osmotic pressure of the solution is reduced to '105^prime 3^3 ~mm Hg'. Determine ne extent of dilution of the solution?
