## Homework Statement

So first the task:

Determine the average value of the kinetic energy of the particles of an ideal gas at 0.0 C and at 100 C (b) What is the kinetic energy per mole of an Ideal gas at these temperatures.

I took the above right out of the pdf we got from our professor.

I know that:

The gas constant is 8.3145 = R

T = Temperature

What got me confused here is that this question seems to be a two-parter. So according to this task I have to find the average kinetic energy for particles AND moles. Is there a difference? Or am I done already?

2. Homework Equations

Ek = 3/2RT --- As far as I can tell.

## The Attempt at a Solution

So far I got down to this:

0.0 C = 273K;

Ek= 3/2 x 8.3145 x 273k =3404.79 J/mol = 3.405 kJ/mol

100 C = 373K

Ek= 3/2 x 8.3145 x 373k =4651.96 J/mol = 4.651 kJ/mol
