Calculate the Z for the fourth ionization of Ti when it requires 425.6 kJ of energy to ionize 0.185 moles of Ti^3+ to Ti^4+ ( The electron being removed is in the outermost valence orbital of Ti^3+ ground state, therefore n = 3)
Can someone please help me with this problem. I'm not sure what to do with the moles that we are given or if we even need them.
