If the molality of the dilute aqueous solution is tripled then the value of molal elevation constant `(K_b)` will become

If molality of the dilute solutions is doubled ,the value of molal depression constant (K_(f)) will be:

For an infinitely dilute aqueous solution molality will be equal to :

The mole fraction of the solute in one molal aqueous solution is:

Why is one molar aqueous solution more concentrated than one molal solution ?

Assertion : Molarity & molality for very dilute aqueous solution is approximately same Reason : For all aqueous solution total mass of solvent is approximately equal to total volume of solution.

Define the following terms : (a) Molarity (b) Molal elevation constant (K_(b))

Define molal elevation constant or ebullioscopic constant.

Molality of an aqueous solution having 0.9 mole fraction of solvent is

The mole fraction of solute in one molal aqueous solution is ………… .

If the mass percentage of urea in an aqueous solution is 20% then molality of the solution will be
