Which law states that the total vapor pressure of a solution containing volatile components is equal to the sum of the partial vapor pressures of the individual components multiplied by their respective mole fractions?

💡 Solution & Explanation

Raoult's law establishes that the partial vapor pressure of each volatile component in an ideal solution equals the vapor pressure of the pure component multiplied by its respective mole fraction in the liquid mixture. Alternative principles like Henry's law govern gas solubility in liquids rather than vapor pressure summation of volatile liquid mixtures. This thermodynamic law applies extensively in chemical engineering and solution chemistry.
