How many moles of alumminum os needed to react woth 6.34 moles of fe3o4 in thereaction below? 8al + 3fe3o4_ 4al2o3 + 9 fe

The moles of Al that is needed to react with 6.34 moles of Fe3O4 is 16.9 moles

Explanation

8 Al + 3Fe3O4 → 4 Al2O3 + 9Fe

use of mole ratio of Al: fe3O4 to calculate the moles of Al

The mole ratio of Fe3O4 : Al is 8:3 therefore the moles of Al =

6.34 moles x8/3 = 16.9 moles
