One mole of any gas at standard temperature and pressure (STP) occupies a volume of:
Correct answer: B. 22.414 dm3
- A. 20.414 dm3
- B. 22.414 dm3
- C. 22.414 cm3
- D. 23.414 dm3
Explanation
A is incorrect as the given volume is not correct under standard conditions.B is correct as the given volume (22.4 dm3) is correct under standard conditions. (fact)C is incorrect as the given volume is not correct under standard conditions.D is incorrect as the given volume is not correct under standard conditions.

About Standard Temperature and Pressure
Standard temperature and pressure provide reference conditions for gas calculations: 0°C or 273 K and, in the usual school convention, 1 atm pressure. Questions use these conditions to relate pressure, volume, temperature and amount of gas, including the molar volume of an ideal gas, about 22.4 dm³.
