Question

23. A mixture of 1.0 mol He and 1.0 mol Ne are at STP in a rigid container. Which of the following statements is TRUE? A) The mixture has a volume of 22.4L B) Both gases have the same average kinetic energy. C) Both gases have the same molecular speed. D) Both gases contribute equally to the density of the mixture under these conditions. E) All of the above are TRUE.
