Parameterization and operation
Molar metal concentration for a compound of iron (12 %) and
aluminum (8 %):
A conversion is performed with the product density for entry in the
RTC module:
The product of the molar concentration [mol/kg] and the density
of the product [kg/L] yields the molar metal concentration in
mol/L. As stated above, this numerical value must be entered for
the metal content. Enter a 1 for the atomic weight of the metal.
