At standard temperature and pressure (STP), what is the volume occupied by 2 mol of chlorine gas (Cl_2)?

• A. 2.0 L
• B. 11.2 L
• C. 22.4 L
• D. 44.8 L

Answer: (D)

Verified step by step guidance

1. Recall that at standard temperature and pressure (STP), one mole of any ideal gas occupies a volume of 22.4 liters. This is a key concept in gas laws and molar volume.
2. Identify the number of moles of chlorine gas given in the problem, which is 2 moles.
3. Use the molar volume relationship to find the total volume occupied by the gas: multiply the number of moles by the molar volume at STP.
4. Write the equation for the volume \(V\) as \(V = n \times 22.4\, \text{L/mol}\), where \(n\) is the number of moles.
5. Substitute \(n = 2\) moles into the equation to find the volume occupied by 2 moles of chlorine gas at STP.
