How many gram of a dibasic acid (Molecular weight 200 g mol^-1) should be present in 100 mL of the aqueous solution to give 0.1 N solution?

A solution has 1 : 4 mole ratio of pentane to hexane. The vapour pressure of the pure hydrocarbons at 20^oC are 440 mm of Hg for pentane and  120 mm of Hg for hexane. The mole fraction of pentane in the vapour phase would be

Which of the following 0.10 M aqueous solutions will have the lowest freezing point?

Which of the following aqueous solutions has minimum freezing point?

 Which one is a colligative property?

If 0.1 M solution of glucose and 0.1 M solution of urea are placed on two sides of the semipermeable membrane to equal heights, then it will be correct to say that

Formation of a solution from two components can be considered as

1. Pure solve → separated solvent molecules, ΔH₃
2. ICl₃ solvent → separated solute molecules, ΔH₂
3. Separated solvent and solute molecules → solution, ΔH₃

Solution so formed will be ideal, if

The lowering of vapour pressure of the solvent takes place on dissolving a non-volatile solute because

The vapour pressure, at a given temperature, of an ideal solution containing 0.2 mole of a non volatile solute and 0.8 mole of solvent is 60 mm of Hg. The vapour pressure of the pure solvent at the same temperature is

Concentrated aqueous sulphuric acid is 98% H₂SO₄ by mass and has a density of 1.80 g mL^-1. Volume of acid required to make one litre of 0.1 M H₂SO₄ solution is
