What is the average kinetic energy of 1 mole of a gas that is at 50 degrees celsius?

4.030 kJ/mol is the average kinetic energy of 1 mole of a gas.

Explanation:

Average energy of 1 mol of gas:

T = temperature of the gas molecule in Kelvins

R = Universal gas constant = 8.314 J/mol K

We have :

T = 50°C = 323.15 K

The average kinetic energy of 1 mole of a gas :

(1 kJ = 1000 J)

4.030 kJ/mol is the average kinetic energy of 1 mole of a gas.

ugh fiel iente of insistí is did kiwis jaj
