0.01 m aqueous solution of sodium sulphate depresses the freezing point of water by 0.0284^@C . Calculate the degree of dissociation of the salt. (k_f of water = 1.86 Km^-1)
A 1% (mass/vol) KCl solution is ionised to the extent of 80%. The osmotic pressure at 27^(@) C of the solution will be :
An aqueous solution boils at 101^(@)C . What is the freezing point of the same solution? (Gives : K_(f) = 1.86^(@)C// m "and" K_(b) = 0.51^(@)C//m )
An aqueous solution of sucrose ( C_(12)H_(22)O_(11) ) having a concentration of 34.2gram/ litre has an osmotic pressure of 2.38 atmospheres at 17^(@) C. For an aqurous solution of glucose ( C_(6)H_(12)O_(6) ) to be isotonic with this solution , its concentration should be :
At 300 K, 36 g of glucose present in a litre of its solution has an osmotic pressure of 4.98 bar. If the osmotic pressure of the solution is 1.52 bars at the same temperature, what would be its concentration?
