Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is 22.4 Litre.
Key Points
- At standard temperature and pressure (STP) one mole of any gas occupies a volume of 22.4 L.
- The standard temperature is 0°C (273.15 K) and the standard pressure is 1 atm.
Important Points
Avogadro’s hypothesis states that:
- Equal volumes of any gas at the same temperature and pressure contain the same number of particles.
The ideal gas equation is:
- PV = nRT
- n=Number of moles
- R=The gas constant.
- The SI value for R is 8.31441 J K-1 mol-1.
