When one mole of non-volatile solute is dissolved in three moles of solvent, the vapour pressure of the solution relative to the vapour pressure of the pure solvent is -

One mole of non-volatile solute is dissolved in two moles of water. The vapour pressure of the solution relative to that water of

One mole of non-volatile solute is dissolved in two mole of water. The vapour pressure of the solution relative to that of water is:

One mole on non-volatile solute is dissolved in two mole of water. The vapour pressure of the solution relative to that of water is:

A non-volatile solute (A) is dissolved in a volatile solvent (B). The vapour pressure of the resultant solution is P_(s^(*)) . The vapour pressure of pure solvent is P_(B)^(@) . If X_(B) is the mole fraction of the solvent, which of the following is correct?

When a solute is dissolved in a solvent the vapour pressure of the solution is decreased. It causes –

When a non volatile solute is dissolved in a solvent, the relative lowering in vapour pressure is equal to

If a non-volatile solute is dissolved in a volatile solvent relative lowering of vapour pressure is equal to
