When calculation concentration in mol.m^-3, and you are given R in m^3 how would you do the conversions?

When calculating concentration in units of mol/m^3 and you are given a pressure in atm, a temperature in Kelvin, and an R value with units of m^3*atm/K*mol, you do not need to do any conversions because the units atm and K should cancel leaving you with a concentration in mol/m^3. Just plug in the R value, pressure, and temperature to solve for the concentration in mol/m^3. Hope this helps!
