Two flexible containers for gases are at the same tem­perature and pressure. One holds 0.50 gram of hy­drogen and the other holds 8.0 grams of oxy­gen. Which of the following statements re­garding these gas samples is FALSE? The volume of the hydrogen container is the same as the volume of the oxygen container. A The number of molecules in the hydrogen con­tainer is the same as the number of molecules in the oxygen container. B The density of the hydrogen sample is less than that of the oxygen sample. C The average kinetic energy of the hydrogen molecules is the same as the average kinetic en­ergy of the oxygen molecules. D The average speed of the hydrogen molecules is the same as the average speed of the oxygen molecules.
