Question

Ratio of partial pressure of gaseous component to total vapour pressure of mixture is

Answer 1

Vx is the partial volume of any individual gas component (X); Vtot is the total volume of the gas mixture; px is the partial pressure of gas X ; ptot is the total pressure of the gas mixture

Answer 2

Dalton's law of partial pressures

The partial pressure of one component of this mixture is the pressure that this individual gas exerts. Dalton's law states that: the total pressure exerted on a container's walls by a gas mixture is equal to the sum of the partial pressures of each separate gas.
