Question

Using the equation below, what mass of iron canbe produced from 10.5 grams of aluminum?Al + FeO → Al2O3 + Fe

Answer 1

Answer:

32.6 grams

Explanations:

Given the reaction between aluminium and ferric oxide as shown;

$2Al+3FeO\rightarrow Al_2O_3+3Fe$

Determine the moles of Aluminium

Mole = Mass/Molar mass

Mole = 10.5/26.98

Mole of Al = 0.3892moles

According to stoichiometry, 2moles of aluminium produced 3 moles of Iron, the moles of Iron needed is given as:

moles of Fe = 3/2 * 0.3892

moles of Fe = 0.5838moles

Determine the mass of iron

Mass of Fe = moles * molar mass

Mass of Fe = 0.5838 * 55.845

Mass of Fe = 32.6grams

Hence mass of iron that can be produced from 10.5 grams of aluminium is 32.6 grams
