||The gas constant, usually denoted by symbol R, occurs in the ideal gas law, as follows: pV=nRT where 'p' is the absolute pressure, 'T' is absolute temperature, 'V' is the volume the gas occupies, 'n' is the amount of gas (usually in moles). The units are Pascal (pressure)×m^3(volume)/(Degrees Kelvin (Temperature)×moles(amount))
