Hi, I have a problem, and I'm not looking for anyone to give me the answers, just a pointer in the right direction would be fantastic. eg. Iron Material Density (g/cm^3) = 7.87 Oxidation State (Z) = 2 Corrosion Current Density (amps/cm^2) = 2.5*10^4 Atomic Weight (g/m) = 55.8 Corrosion Rate = ?? We're given a list of equations, as follows - Rate= j/nF density = m/v o= Ee F = 96,500 Coul/mol o= F/Ao 1 MPa = 10^6 N/m^2 I have no idea which equations to use even, I'm very new to physics, and would appreciate anyone who can help me out, because I want to be able to solve (and understand!!) how to figure it out. Thankyou!
