Recap - Smelter

Part of the Oxidation and Reduction section of Coddy's Chemistry journey. Lesson 24 of 27.

Challenge

A school demonstration smelter electrolyzes $510\ \mathrm{g}$ of aluminum oxide, Al₂O₃ (102 g/mol), dissolved in molten cryolite: 2Al₂O₃ → 4Al + 3O₂. What mass of aluminum, mAl, does it make? (Al, 27 g/mol)

Try it yourself

Solve for $m_{Al}$
