Find the mole fraction of 10% NaOH solution.

Define mole fraction .

What is the molarity of 10% (w/v) NaOH solution?

The vapour pressure of a solvent decreased by 10 mm. of Hg when a non-volatile solute was added to the solvent. The mole fraction of solute in solution is 0.2, what would be the mole fraction of solvent if decrease in vapour pressure is 20 mm of Hg:

For the mixture of gases in equilibrium with a liquid, how is the partial pressure of the gas is related to the mole fraction of the gas in the solution.

The mole fraction of water in a solution containing 50 g of water and 50 g of ethyl alcohol is:

If mole fraction of the solvent in a solution decreases then:
