WebThis definition is now obsolete. The preferred definition, since 1982, is 273.15 K and 1 bar (100 kPa = 750.06 Torr) (134,135). The National Institute of Standards and Technology, on the other hand, defines STP as 1 atm and 20 ᵒC (293.15 K, or 68 ᵒF). In practical applications of adsorption equipment, STP often refers to the pressure of the ... Web( 1 atm ≡ 760 mmHg) STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP = 0 ∘ C, 1 atm, where the molar volume = 22.4 L / mol. If the reference pressure is chosen to be 1 bar, the molar volume is 22.7 L / mol. Do ...
