Answer:
Explanation:
- The conditions given to determine the volume which are 0ºCelsius and 1 atmospheric pressure together are called Standard Temperature and Pressure or STP.
- Any gaseous object at STP has a volume of 22.4 litres and has only one mole of it. This is also called the molar weight. This can be further determined by using the equation of the ideal gas law which requires P (pressure), V (volume), n (number of moles), R (universal gas constant) and t (temperature).
Eqn:
PV = nRT............
