How many moles of al are needed to react completely with 1.2 moles of fe0

 3 moles of feO  gives you  2 moles of Al and 1.2 of your moles should give you 1.2 divided by 3*2 so it equals 0.80 moles 

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

the electrical  conductivity  of asolution  of an electrolyte is measured by determining the resistance of thesolution  between two flat or cylindrical electrodes separated by a fixed distance.
