One of the main components of rust is a hydrated iron (III) oxide – Fe2O3•nH2O. This compound can react with acids such as hydrochloric acid. The unbalanced reaction is shown below: Fe2O3•nH2O(s) + HCl(aq) FeCl3(aq) + H2O(l) If it takes 103 mL of 1.25 M HCl to completely react with 5.00 grams of Fe2O3•nH2O then what is the value of n? You must show all of your work to receive any credit. Round your value of n to the...
