Raoult's law states that for a dilute solution,
A.the lowering of vapour pressure is equal to the
B.the relative lowering of vapour pressure is
C.the relative lowering of vapour pressure is equal to✓ Correct
D.the vapour pressure of the solution is equal to the
Explanation
According to Raoult’s Law for dilute solutions states that, for non-volatile solute, the relative lowering at vapor pressure is equal to the mole fraction of solute. Thus, the correct option is (c) the relative lowering of vapor pressure is equal to the mole fraction of the solute.
