If a litre of CO 2 is compared to a litre of H 2 , both at 25°C and one atmosphere pressure, then: a) there are more H 2 molecules than CO 2 molecules b) the CO 2 molecules are on the average moving more slowly than the H 2 molecules c) the mass of one liter of CO 2 equals the mass of one liter of H 2 d) the average kinetic energy of the CO 2 molecules is greater than that of the H 2 molecules e) the CO 2 and H 2 molecules have the same average speed 2) A 5.00 L container of unknown gas at 25.0 °C has a pressure of 2.45 atm. The mass of the gas is 32.1 g. What gas is in the container? a) NO 2 b) Cl 2 c) SO 2 d) F 2 e) SO 3 3) Consider the following reaction: N 2 (g) + 3 H 2 (g) 2 NH 3 (g) What volume of NH 3 (g) can be produced from 200.0 L of H 2 (g) if the gases are measured at 350 °C and 400 atm pressure? a) 133.3 L b) 200.0 L c) 66.7 L d) 400.0 L e) 300.0 L 4) Calculate the temperature at which the root-mean-square velocity of carbon dioxide (CO 2 ) molecules is 500 m s -1 . a) 714°C b) 414°C c) 441°C d) 168°C e) 1.62°C 5) Calculate the height of a column of liquid glycerol ( d = 1.26 g/cm 3 ), in meters, required to exert the same pressure as 4.91 m of water. a)
