One mole of an ideal gas occupies a volume of ______ litre at 273 K and 1 atm pressure

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 22.4.

  • The value of the proportionality constant R, can be calculated from the fact that exactly one mole of a gas at exactly 1 atm and at 0 ˚C (273 K) has a volume of 22.414 L.

  • Standard pressure is 1.00 atmospheres and standard temperature is 273 kelvin.

  • The ideal gas law is PV=nRT.
