Determine the osmotic pressure of a solution prepared by dissolving 25 mg of `K_(2)SO_(4)` in two litre of water at `25^(@)C` assuming that it is completely dissociated.

The measured osmotic pressure of a soultion prepared by dissolving 17.4 mg of K_(2)SO_(4) in 2L of water at 27^(@)C" is "3.735xx10^(-3) bar. The van't Hoff factor is ( R =0.083 L" bar "K^(-1) mol^(-1) , atomic weights k=39, S=32, O=16)

Calculate the osmotic pressure in pascals exerted by a solution prepared by dissolving 1.0 g of polymer of molar mass 185,000 in 450 mL of water at 37^(@)C

9.8 g of H_(2)SO_(4) is present in two litres of a solution. The molarity of the solution is,

At 10^@C , the osmotic pressure of urea solution was formed to be 500 mm. The solution is diluted 'x' times and the temperature raised to 25^@C when the osmotic prssure was noticed to be 105.3mm, then 'x' is

100 mL of 1.5% (w/v) solution of urea is found to have an osmotic pressure of 6.0 atm and 100 mL of 3.42% (w/v) solution of cane sugar is found to have an osmotic pressure of 2.4 atm. If the two solution are mixed the osmotic pressure of the resulting solution in atm is Assume that there is no reaction between urea and cane sugar )

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^(@)C .
