Which law states that the total pressure exerted by a mixture of non-reactive gases is equal to the sum of the partial pressures of individual gases?

💡 Solution & Explanation

Dalton's Law of Partial Pressures establishes that the total pressure exerted by an ideal gas mixture is equal to the arithmetic sum of the partial pressures each gas would exert if it occupied the volume alone. Alternative laws like Boyle's law and Charles's law describe pressure-volume and volume-temperature relationships for single gases rather than multi-gas mixtures. General science questions frequently utilize this law to calculate dry gas pressures collected over water.
