Answer:
The mass of air stored in the vessel is 235.34 kilograms.
Explanation:
Let supossed that air inside pressure vessel is an ideal gas, The density of the air (), measured in kilograms per cubic meter, is defined by following equation:
(1)
Where:
- Pressure, measured in kilopascals.
- Molar mass, measured in kilomoles per kilogram.
- Ideal gas constant, measured in kilopascal-cubic meters per kilomole-Kelvin.
- Temperature, measured in Kelvin.
If we know that ,
,
and
, then the density of air is:
The mass of air stored in the vessel is derived from definition of density. That is:
(2)
Where is the mass, measured in kilograms.
If we know that and
, then the mass of air stored in the vessel is:
The mass of air stored in the vessel is 235.34 kilograms.
