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 N_2 gas is passed through water at 293 K, how many moles of 1N_2 would dissolve in one litre water ? Assume that N_2 exert a partial pressure of 0.987 bar. K_H for N_2 at 293 K is 76.48 kilobar.

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 molal b.pconstant '(fK_h)' for water is '0.513^circ C' kgmol". When 0.1 mole of sugar is dissolved 'in '200 ~g' of water, the solution boils under a pressure of 1 atm. At

.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.

Two solutions of glucose have osmotic pressures 1.5 and 2.5 atm. 1 litre of first solution is mixed with 2 litre of second solution. The osmotic pressure of the resultant solution will be:

What will happen to the volume of a bubble of air found under water in a lake where the temperature is 15°C and the pressure is 1.5 atm, if the bubble then rises to the surface where the temperature is 25^(@)C and pressure is 1 atm

A sample of HI(g) is placed in a flask at a pressure of 0.2 atm. At equilibrium, the partial pressure of HI(g) is 0.04 atm. What is K_p for the equilibrium 2HI(g) iff H_2(g)+I_2(g)

A vessel of '1000 K' contains 'CO_2', with a pressure of '0.5 atm .' Some of the 'CO_2' converted into 'CO' on the addition of graphite. The value of 'K' if the total pressure at equilibrium is '0.8 atm'. is:
