The total pressure in a system with 50 heavy gas particles and 150 light gas particles is approximately 14.8 atm, calculated by summing the partial pressures of each gas based on their mole fractions.
The partial pressure of a gas is proportional to its mole fraction in the mixture, which is the ratio of the number of moles of that gas to the total number of moles of all gases in the mixture1.
From Table 2, we can see that the pressure for heavy particles is 5.4-5 atm when the number of gas particles is 50, and the pressure for light particles is 17.9-18 atm when the number of gas particles is 150. Therefore, the partial pressures of heavy and light gas particles are:
P heavy = 5.4-5 atm * (50/200) = 1.35-1.25 atm P light = 17.9-18 atm * (150/200) = 13.425-13.5 atm
The total pressure of the system is the sum of the partial pressures of heavy and light gas particles:
P total = P heavy + P light = 1.35-1.25 atm + 13.425-13.5 atm = 14.775-14.75 atm
Therefore, the total pressure of a system containing 50 heavy gas particles and 150 light gas particles is approximately 14.8 atm.
