how many moles of iron will be produced from 6.20 moles of carbon monoxide reacting with excess iron (III) oxide (FeO3) to produce 11.6 g of iron (Fe)

Respuesta :

0.20 moles of iron will be formed in the reaction.

Explanation:

The balanced chemical equation for the reaction between iron (iii) oxide and carbon monoxide to form Fe is to be known first.

the balanced reaction is :

Fe2O3 + 3CO⇒ 2 Fe + 3 CO2

so from the data given the number of moles of carbon monoxide can be known:

3 moles of CO reacted with Fe2O3 to form 2 moles of iron in the reaction.

Number of moles of CO is 6.20 moles

11.6 gm of iron is formed

so the number of moles of iron formed is calculated as

n = mass of iron ÷ atomic weight of iron

  = 11.6 ÷ 55.84

  = 0.20 moles of iron will be formed when 11.6 gram of iron is produced.

The moles of Iron produced in the chemical reaction has been 0.2 mol.

The moles of product formed and reactant consumed has been given by the stoichiometric values of the balanced chemical equation.

The given balanced chemical equation has been:

[tex]\rm 3\;CO\;+\;Fe_2O_3\;\rightarrow\;2\;Fe\;+\;3\;CO_2[/tex]

Computation for moles of Iron produced

The molar mass of Fe has been 55.85 g/mol.

The mass of Fe produced in the chemical reaction has been 11.6 g.

The moles of Fe produced has been:

[tex]\rm Moles=\dfrac{Mass}{Molar\;mass}\\\\ Moles\;Fe=\dfrac{11.6\;g}{55.85\;g/mol}\\\\ Moles\;Fe=0.20\;mol[/tex]

The moles of Iron produced in the chemical reaction has been 0.2 mol.
