Which of the following is the correct value of the molar volume of an ideal gas at standard temperature and pressure (STP)?
Show Hint
At STP, the molar volume of an ideal gas is 22.4 L/mol. This is true for all ideal gases.

The Correct Option is A
Solution and Explanation
At standard temperature and pressure (STP), the molar volume of an ideal gas is always 22.4 L/mol. This is derived from the ideal gas law, where 1 mole of an ideal gas occupies 22.4 L at 0°C (273 K) and 1 atm pressure.
Thus, the correct molar volume at STP is 22.4 L/mol, corresponding to option (1).
