A molal solution is one that contains 1 mol of a solute in

A

`1000 g` of `solvent`

B

`1 L` of solvent

C

`1 L` of solution

D

`22.4 L` of solution

Text Solution

Verified by Experts

The correct Answer is:
A

The number of moles of the solute present per kilogram of the solvent is known as its molality.
`m=(W_("solute"))/(Mw_("solute")) xx 1/W_("solvent in kg")`
=`(W_("solute"))/(Mw_("solute")) xx 1/W_("solvent in g")xx 1000`

A molal solution is one that contains one mole of a solute in

A molal solution is one that contains one mole of a solute in:

A dilute solution contains m mol of solute A in 1 kg of a solvent with molal elevation constant K_(b) . The solute dimerises in solution as 2AhArrA_(2) Select the correct expression of equilibrium constant 'K' for the dimer formation. (assume molarity = molality)

A dilute solution contains 'x' moles of solute A in 1 kg of solvent with molal elevation constant K_(b) . The solute dimerises in the solution according to the following equation. The degree of association is (a) : 2A hArrA_(2) The degree of assoicition is equal to :

A: 1M solution and 1 molal solution contain same mass of solute. R: 1M and 1m aqueous solution are equally concentrated.

Mole fraction fo solvent in an aqueous solution is 0.8. What is the molality of this solution in mol/kg?

Mole fraction of solvent in an aqueous solution is 0.7. What is the molality of this solution in mol/kg?

Calculate the molality of a solution containing 8 moles of sucrose in 250 g of solvent.

For [CrCl_(3).xNH_(3)] , elevation in boiling point of the one molal solution is triple of one molal aqueous solution of urea. Assuming 100% ionisation of complex molecule, calculate the value of x.

For [CrCl_(3).xNH_(3)] , elevation in boiling point of one molal solution is double of one molal solution of glucose , hence x is if complex is 100% ionised :
