Molecular Speeds: a Sealed Container Holds 0

question 15

Multiple Choice

Molecular speeds: A sealed container holds 0.020 moles of nitrogen (N₂) gas at a pressure of 1.5 atmospheres and a temperature of 290 K. The atomic mass of nitrogen is 14 g/mol. The Boltzmann constant is 1.38 × 10^-23 J/K and the ideal gas constant is R = 8.314 J/mol ∙ K = 0.0821 L ∙ atm/mol ∙ K. The average translational kinetic energy of a nitrogen molecule is closest to

• A) 4.0 × 10^-21 J.
• B) 6.0 × 10^-21 J.
• C) 8.0 × 10^-21 J.
• D) 10 × 10^-21 J.
• E) 12 × 10^-21 J.
