Convert the concentration \(\frac{\text{mmol}}{\text{g}}\) to \(\frac{\mu\text{mol}}{\text{m}^2}\).
This is done by dividing the concentration per gram by the material surface per gram property \(S_\text{BET}\)
Concentration in \(\frac{\text{mmol}}{\text{g}}\)
Material surface in \(\frac{\text{m}^2}{\text{g}}\)
Concentration in \(\frac{\mu\text{mol}}{\text{m}^2}\)
