Question SLPaper 1AAnswerA sealed container contains a mixture of oxygen and nitrogen gas. The ratio mass of an oxygen moleculemass of a nitrogen molecule=87\frac{{\text{{mass of an oxygen molecule}}}}{{\text{{mass of a nitrogen molecule}}}} = \frac{8}{7}mass of a nitrogen moleculemass of an oxygen molecule=78. The ratio average kinetic energy of oxygen moleculesaverage kinetic energy of nitrogen molecules\frac{{\text{{average kinetic energy of oxygen molecules}}}}{{\text{{average kinetic energy of nitrogen molecules}}}}average kinetic energy of nitrogen moleculesaverage kinetic energy of oxygen molecules is:A1B78\frac{7}{8}87C87\frac{8}{7}78Ddependent on the concentration of each gas
