WebJul 1, 2024 · The volume of 1.00mol of any gas at STP (Standard temperature, 273.15 K and pressure, 1 atm) is measured to be 22.414L. We can substitute 101.325kPa for pressure, 22.414 L for volume, and 273.15 K for temperature into the ideal gas equation and solve for R. R = PV nT = 101.325kPa × 22.414L 1.000mol × 273.15 K = 8.314kPa ⋅ L/K ⋅ mol Web(T/F) The two properties used most often for identifying specific conditions of the air are temperature and humidity.
