Answer:

Well the molar mass of ferric oxide, #Fe_2O_3#, is #159.69*g*mol^-1#....

Explanation:

But iron has a particularly rich oxidation chemistry. We don't know whether all the #16*kg# mass was ferric oxide, or ferrous oxide, or #Fe_3O_4# or hydrous iron oxides.....Clearly you can work out the molar quantity if all the rust is present as #Fe_2O_3#....

#"Moles of ferric oxide"=(16xx10^3*g)/(159.69*g*mol^-1)=??mol.#
