Answer:
Partial Pressure of X = 0.45 atm
Partial Pressure of Y = 1.05 atm
Explanation:
Mixture of gas = Gas X + Gas Y
Total number of moles = 3 + 7 = 10 moles
Total pressure = 1.50 atm
The relationship between partial pressure, total pressure and number of moles is given as;
Partial pressure of gas X / Total pressure = Number of moles of gas X / Total number of moles
Partial Pressure of gas X / 1.50 = 3 / 10
Partial Pressure of gas X = 1.5 * 3 / 10 = 0.45 atm
The total pressure of a mixture is a sum total of the individual pressures, hence;
Pressure of mixture = Partial Pressure of X + Partial pressure of Y
1.5 = 0.45 + Partial pressure of Y
Partial Pressure of Y = 1.5 - 0.45 = 1.05 atm
