Help with equation


I have Gibs adsorption equation:

a=-C/RT*ds/dC

where C is concentration in mol/L,
R-universal gas constant
T-Temperature in Kelvins
s- surface tension N/m

What units will be a? I think mol/dm^2?

Concentration drops out, so it becomes [R]<sup>-1</sup>[T]<sup>-1</sup>[s] = J<sup>-1</sup> K mol K<sup>-1</sup> N m<sup>-1</sup> = kg<sup>-1</sup> m<sup>-2</sup> s<sup>2</sup> kg m s<sup>-2</sup> m<sup>-1</sup> mol = m<sup>-2</sup> mol

or mol per square meter.
