Answer:

The average KE = 312 J/mol

Explanation:

Given:

Temperature of the gas, T = 285 K

Gas constant, R = 8.314 J/K-mol

To determine:

The average kinetic energy of the gas

Explanation:

Based on the kinetic theory of gases, the average kinetic energy is given as:

[tex]KE = \frac{3}{2} RT\\[/tex]

In this case:

[tex]KE = \frac{3}{2} *8.314\ J/K-mol * 285\ K = 312 J/mol[/tex]
