What is the internal energy of 2.0 mol of an ideal monatomic gas at 273 K?

Explanation

To find the internal energy of 2.0 mol of an ideal monatomic gas at 273 K, we can use the formula for the internal energy (U) of an ideal gas:

\[ U = \frac{f}{2} nRT \]

Where:
- \( U \) is the internal energy,
- \( f \) is the degrees of freedom,
- \( n \) is the number of moles,
