Final answer:
The partial pressure of gas x in kPa is equal to Px = Xx * Pt. According to Dalton's law, the partial pressure of a gas is proportional to its mole fraction (X). For example, if the mole fraction of gas x is 0.4 and the total pressure of the gas mixture is 100 kPa, the partial pressure of gas x would be 0.4 * 100 kPa = 40 kPa.
Step-by-step explanation:
The partial pressure of gas x in kPa is equal to Px = Xx * Pt.
According to Dalton's law, the partial pressure of a gas is proportional to its mole fraction (X). The mole fraction is the number of moles of the gas divided by the total number of moles of all components in the gas mixture.
For example, if the mole fraction of gas x is 0.4 and the total pressure of the gas mixture is 100 kPa, the partial pressure of gas x would be 0.4 * 100 kPa = 40 kPa.
