R bar chemistry
WebJan 13, 2024 · R is gas constant, but the units can be different like atm, torr, or bar. The ideal gas law is PV = nRT, where n is the number of moles, and R is universal gas constant. The value of R depends on the units involved, but is usually stated with S.I. units as: R = 8.314 J/mol. It is just a constant to use in the equation.
