A Sealed Container Holds 0 $\left( \mathrm { N } _ { 2 } \right)$

question 73

Multiple Choice

A sealed container holds 0.020 moles of ideal nitrogen $\left( \mathrm { N } _ { 2 } \right)$ gas, at a pressure of 1.5 atm and a temperature of 290 K. The atomic mass of nitrogen is 14.0 g/mol. What is the average translational kinetic energy of a nitrogen molecule? The Boltzmann constant is $1.38 \times 10 ^ { - 23 } \mathrm {~J} / \mathrm { K }$

• A) \(4.0 \times 10 ^ { 21 } \mathrm {~J}\)
• B) \(8.0 \times 10 ^ { 21 } \mathrm {~J}\)
• C) \(12 \times 10^{21} \mathrm {~J}\)
• D) \(6.0 \times 10^{21} \mathrm {~J}\)
• E) \(10 \times 10^{21} \mathrm {~J}\)
