Question

A sealed container holds 0.020 moles of ideal nitrogen (N2) 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 x 10^-23 J/K.

Explanation / Answer

KE= 0.5*k*T

= 0.5*1.38*10-23 *290

=  6.0 x 10-21 joule
