Asked by Dylan
I am confused with these 2 questions can someone help me solve them?
1. If a current of 18.62 A flows for 18.15 hr, then how many moles of electrons have flowed?
2. Find ΔGo in J for: Al3+(aq) + 3e- → Al(s) Eo = -1.66 V

Coulombs = amperes x seconds = 18.62 A x 18.15 hrs x (60 min/hr) x (60 sec/min) = ?
Then 1 mole electrons = 96,485 coulombs.
2. dGo = -nFEo = -3*96,485*(-1.66) = ?
