Question

Which of the following is the correct value of the molar volume of an ideal gas at standard temperature and pressure (STP)?

• A. 22.4 L/mol
• B. 22.8 L/mol
• C. 24.0 L/mol
• D. 20.0 L/mol

Hint:

At STP, the molar volume of an ideal gas is 22.4 L/mol. This is true for all ideal gases.

Answer 1

The Correct Option is A

The molar volume of an ideal gas at standard temperature and pressure (STP) is consistently 22.4 L/mol. This value originates from the ideal gas law, which states that 1 mole of an ideal gas occupies 22.4 L under conditions of 0°C (273 K) and 1 atm pressure. Consequently, the established molar volume at STP is 22.4 L/mol, aligning with option (1).
