Which of the following best describes the volume occupied by 1 mol of an ideal gas at standard temperature and pressure (STP)?

• A. 22.4 L
• B. 0.0821 L
• C. 1.0 L
• D. 273 L

Answer: (A)

Verified step by step guidance

1. Recall that standard temperature and pressure (STP) is defined as a temperature of 0°C (273 K) and a pressure of 1 atm.
2. Understand that 1 mole of an ideal gas at STP occupies a specific volume, which can be derived from the Ideal Gas Law: \(P \times V = n \times R \times T\).
3. Write down the Ideal Gas Law formula with the known values: \(P = 1\) atm, \(n = 1\) mol, \(R = 0.0821\) L·atm/(mol·K), and \(T = 273\) K.
4. Rearrange the Ideal Gas Law to solve for volume \(V\): \(V = \frac{n \times R \times T}{P}\).
5. Substitute the known values into the equation to find the volume occupied by 1 mole of an ideal gas at STP, which will give you the volume closest to one of the provided options.
