Requirements for selecting volume conversion constants
Thread Content
In the calculation of the volume of sulfuric acid-containing flue gas, material volume conversion is involved; I usually use a value of 22.4, but some technicians prefer to use 21.89. When is it appropriate to use 22.4 and when is it suitable to use 21.89? Are there any fundamental guidelines for this? .
It’s always 22.414 for me. How is 21.89 obtained?
21.89 is the molar volume of elemental sulfur dioxide.
Under standard conditions, 1 mole of any gas occupies a volume of approximately 22.4 L.
With the exception of sulfur dioxide, 1 mol of SO2 occupies only 21.89 L under standard conditions
