The composition of an ideal gas mixture, by mass, is 25% nitrogen (N2), 25% carbon dioxide (CO2) and 50% oxygen (O2). The apparent gas constant of the mixture, in kJ/kg. K, is (write your answer with three decimal points; for example if the answer is 0.2876 kJ/kg. K write 0.288; if the answer is 0.2802 kJ/kg. K write 0.280; do not include the units in your answer)

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
