One of the most destructive natural processes in civilization is the corrosion of iron in the presence of oxygen to form rust, which for simplicity can be taken to be iron(III) oxide. If a cubic block of iron of side 1.5 cm reacts with 15.5 L of oxygen at 1.00 atm and 25°C, what is the maximum mass of iron(III) oxide that can be produced? Iron metal has a bcc structure, and the atomic radius of iron is 124 pm. The reaction takes place at 298 K and 1.00 atm.
