What is the internal energy (to the nearest joule) of 10 moles of Oxygen at 100 K? (Given, the universal gas constant = 8.315 J/(mol. k))

U = 12,205.5 J

Explanation:

In order to calculate the internal energy of an ideal gas, you take into account the following formula:

       (1)

U: internal energy

R: ideal gas constant = 8.135 J(mol.K)

n: number of moles = 10 mol

T: temperature of the gas = 100K

You replace the values of the parameters in the equation (1):

The total internal energy of 10 mol of Oxygen at 100K is 12,205.5 J
