**Question:**

A large balloon is initially filled with 1.00 mole of gas which has a volume of 22.0 L at 273 K and a pressure of 1.00 atm. What is the experimental ideal gas constant at this condition?

**Explanation:**

To determine the experimental ideal gas constant \( R \) under the given conditions, we can use the Ideal Gas Law, which is expressed as:

\[ PV = nRT \]

In this equation:
- \( P \) is the pressure,
- \( V \) is the volume,
- \( n \) is the number of moles,
- \( R \) is the ideal gas constant,
- \( T \) is the temperature in Kelvin.

Given:
- \( P = 1.00 \) atm,
- \( V = 22.0 \) L,
- \( n = 1.00 \) mole,
- \( T = 273 \) K.

Rearranging the Ideal Gas Law to solve for \( R \):

\[ R = \frac{PV}{nT} \]

Substituting the given values:

\[ R = \frac{(1.00 \, \text{atm}) \times (22.0 \, \text{L})}{(1.00 \, \text{mol}) \times (273 \, \text{K})} \]

Calculate \( R \) to find the experimental ideal gas constant.
