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.
