Answer:
[tex]K=18.70kJ[/tex]
Explanation:
The kinetic energy of an ideal gas is defined as:
[tex]K=\frac{3}{2}nRT[/tex]
Here n is the number of moles of the gas, R is the ideal gas constant and T is the temperature of the gas. So, replacing the given values, we get the kinetic energy of the system:
[tex]K=\frac{3(5mol)(8.31\frac{J}{mol\cdot K})(300K)}{2}\\K=18697.5J=18.70kJ[/tex]
