How many grams of Al are needed to react with 63.0 g of FeO
Tema [17]

The amount of Al required will be 15.77 grams

<h3>Stoichiometric problem</h3>

First, the equation of the reaction:

2Al +3 FeO -- > Al_2O_3 + 3Fe

The mole ratio is 2:3.

Mole of 63.0 g of FeO = 63/71.84 = 0.8769 moles

Equivalent moles of Al = 0.8769 x 2/3 = 0.5846 moles

Mass of 0.5846 moles Al = 0.5846 x 26.98 = 15.77 grams
