For calculating mass from ideal gas equation, absolute or gauge pressure should be used ?

Answers

Answered by avj65617

It is absolute pressure.

It is absolute pressure.
It cannot be gauge pressure, because gauge pressure can be zero or even negative. Plugging in zero into the equation gives either T or n to be zero. This is not possible for a given volume of gas.
