Provide the different values and units of the universal gas constant $R$.

(N/A) The universal gas constant $R$ is defined by the ideal gas equation $PV = nRT$,which implies $R = \frac{PV}{nT}$. Its value depends on the units used for pressure,volume,and temperature. The following table summarizes the common values of $R$:

Condition	Value and Unit of $R$
$(i)$ Pressure in $atm$,Volume in $L$	$0.0821 \ L \ atm \ K^{-1} \ mol^{-1}$
$(ii)$ Pressure in $bar$,Volume in $L$	$0.08314 \ L \ bar \ K^{-1} \ mol^{-1}$
$(iii)$ $SI$ Units (Pressure in $Pa$,Volume in $m^3$)	$8.314 \ J \ K^{-1} \ mol^{-1}$
$(iv)$ Energy in $calories$	$1.987 \ cal \ K^{-1} \ mol^{-1}$
