The gas constant is also known as the molar, universal, or ideal gas constant, denoted by the symbol R or R and is equivalent to the Boltzmann constant, but expressed in units of energy per temperature increment per mole, i.e. the pressure-volume product, rather than energy per temperature increment per particle.
According to the Ideal Gas Law
PV = nRT
P is pressure (pascal or N/m2 or kg/m/s2)
V is volume (m3)
n is number of moles (moles)
R is the Gas Constant (need to find out)
T is temperature (Kelvin K)
R = PV / nT
= ( Kg/m/s2 x m3 ) / ( mole x K )
= ( Kg.m2/s2 ) / ( mole x K )
Now 1 Joule = 1 Kg.m2 / s2
So, the dimensions are Mass L^2 Time^-2 Temp^-1 Mol^-1.
