0.0008516 moles of carbon monoxide are needed to react completely with 136 kg of Fe₂O₃.
A mole corresponds to the mass of a substance that contains 6.023 x [tex]10^{23}[/tex] particles of the substance.
From the equation:
[tex]Fe_2O_3(s) + 3CO(g)[/tex] →.[tex]2Fe(s) + 3CO_2(g)[/tex]
1 mole Fe₂O₃ needs 3 moles of CO
Find moles of Fe₂O₃
Given mass of Fe₂O₃= 136 kg
Molar mass of Fe₂O₃= 159.69 g/mol
Moles of Fe₂O₃ = [tex]\frac{mass}{molar \;mass}[/tex]
Moles of Fe₂O₃ = [tex]\frac{0.136 g}{159.69 g/mol}[/tex]
Moles of Fe₂O₃ = 0.0008516
0.0008516 moles require:
= 0.0008516 x 3
= 0.0008516 moles of CO
0.0008516 moles of carbon monoxide are needed to react completely with 136 kg of Fe₂O₃.
