Question

A gas mixture consists of 32 gram of oxygen and 36 gram of ar a temperature t. neglecting all vibration modes, the total internal energy of the system is

Answer 1

is very difficult data quality it is not possible to frame national policy

Answer 2

Given:

Amount of oxygen available = 32 g

Amount of  Ar available = 36 g

To find

the total internal energy of the system

Explanation:

To find the total energy of the system

Now we have formula n (F/2) RT

              =  n (F/2) RT

On substituting the given values ,we get -

              = 2× (5/2) RT + 4 × (3/2) RT

              = 11 RT

Answer = 11 RT.
