Question

Which of the following formula represents Raoult's law for a solution containing non-volatile solute?

Options

• `"p"_"solute" = "p"_"solute"^\circ * "x"_"solute"`

• `"p" = "K"_"H" * "x"`

• `"p"_"Total" = "p"_"solvent"`

• `"p"_"solute" = "p"_"solvent"^\circ * "x"_"solvent"`

Answer 1

`bb("p"_"Total" = "p"_"solvent")`

Explanation:

At a given temperature, the mole fraction of the solvent in a solution containing a nonvolatile solute is directly proportional to the solution's vapour pressure.
