Question

Given the balanced equation below, calculate the moles of aluminum that are needed to react completely with 28.7 moles of FeO. You must show all of your work. 2Al + 3FeO --> 3Fe +Al2O3

Answer 1

43.05 moles of Al needed to react with 28.7 moles of FeO.

Step-by-step explanation:

Given data:

Moles of FeO = 28.7 mol

Moles of Al needed to react with FeO = ?

Solution:

Chemical equation:

2Al + 3FeO → 3Fe + Al₂O₃

Now we will compare the moles of Al with FeO.

FeO : Al

2 : 3

28.7 : 3/2×28.7 = 43.05 mol

Thus 43.05 moles of Al needed to react with 28.7 moles of FeO.
