How many kilograms of aluminum can be extracted from 2.0 metric tons of the ore 'alumina' (Al2O3)?
Answered by Nathalie
Would you take the percentage of aluminum in the ore:

53.96/101.96 = 52.92

then take that much out of 2.0 metric tons or 2000 kg?

So would it be 1058.40 kilograms?
Answered by DrBob222
Convert 2.0 metric tons Al2O3 to grams Al2O3.
Convert grams Al2O3 to mols Al2O3.
Convert mols Al2O3 to mols Al knowing that there are 2 mols Al for every mol Al2O3.
Convert mols Al to grams Al remembering that mols x atomic mass = grams.
Finally, convert grams Al to kg Al.
Check my thinking.

Post your work if you get stuck.
