Question

How much aluminum oxide is needed to produce 1.000 kg of aluminum?

Answer 1

Well how many moles of aluminum will you be requiring?

Explanation:

`"Moles of aluminum"=(1.000*kgxx10^3*g*kg^-1)/(27.0*g*mol^-1)`

`=37.0*mol`...

And to reduce alumina, we follow the equation....

`Al_2O_3+6H^+ +6e^(-) rarr 2Al(s) + 3H_2O`

And so we need `(37.0*mol)/2xx101.96*g*mol^-1=1.89*kg`..with respect to alumina...
