Given the balanced equation below, calculate the moles of aluminum that are needed to react completely with 17.5 moles of FeO? Show all work

2Al+3FeO->3Fe+Al2O3

The moles of Al that are needed to react completely with 17.5 moles of FeO is 11.67 moles

calculation

2Al + 3 FeO → 3 Fe + Al₂O₃

The moles of Al is calculate using the mole ratio

That is; From equation above the mole ratio of Al : FeO is 2:3 therefore the moles of Al

= 17.5 moles x 2/3 = 11.67 moles
