Equal masses of three different ideal gases, X, Y, and Z, are mixed in a sealed rigid container. If the temperature of the system remains constant, which of the following statements about the partial pressure of gas X is correct?
a) It is equal to 1/3 of the total pressureb) It depends on the intermolecular forces of attraction between molecules of X, Y, and Zc) It depends on the relative molecular masses of X, Y, and Zd) It depends on the average distance traveled between molecular collisionse) It can be calculated wiht knowledge only of the volume of the container
