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) :
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
All form ideal solution except
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)
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 –
If all the four following compounds were sold at the same price, which would be cheapest for preparing an antifreeze solution for a car radiator?
18 g of glucose (C6H12O6) is added to 178.2 g of water. The vapour pressure of water for this aqueous solution is
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
For which of the following parameters the structural isomers C2H5OH and CH3OCH3 would be expected to have the same values?(Assume ideal behaviour)
