The molal freezing point constant for water is 1.86 ºC. Therefore, the change in freezing point of 0.1 molal of NaCl solution in water is expected to be
18 g of glucose (C6H12O6) is added to 178.2 g of water. The vapour pressure of water for this aqueous solution is
All form ideal solution except
An ideal solution is formed when its components
If 0.44 g of substance dissolved in 22.2 g of benzene lowers the freezing point of benzene by 0.567 ºC, then the molecular mass of substance is, the molal depression constant = 5.12 ºC mol–1
For which of the following parameters the structural isomers C2H5OH and CH3OCH3 would be expected to have the same values?(Assume ideal behaviour)
When 10 g of a non-volatile solute is dissolved in 100 g of benzene, it raises boiling point by 1ºC then molecular mass of the solute is (Kb for benzene = 2.53 km–1)
An aqueous solution containing 1 g of urea boils at 100.25 ºC. The aqueous solution containing 3 g of glucose in the same volume will boil at (mol. wt. of urea = 60 and of glucose = 180) :
The value of P° for benzene is 640 mm of Hg. The vapour pressure of solution containing 2.5 g substance in 39 g. benzene is 600 mm of Hg the molecular mass of X is –
