Answer:
2.66 g of Fe, can be obtained from the reaction
Explanation:
Let's think the reaction:
2Fe₂O₃ + 6CO → 4Fe + 6CO₂
Ratio is 2:4, so If i have x moles of iron (III) oxide, I will produce the double of moles of Fe.
Mass / Molar mass = Mol
3.80 g / 159.7 g/m = 0.0237 moles
0.0237 moles . 2 = 0.0475 moles
Molar mass Fe = 55.85 g/m
Mol . Molar mass = Mass → 0.0475 m . 55.85 g/m = 2.66 grams
2 moles of Iron oxide produce, 4 moles of iron hence the molar ratio is 1:2. The mass of iron obtained from 3.08 g of iron(III) oxide is 2.66 g.
The reaction:
[tex]\bold {2Fe_2O_3 + 6CO \rightarrow 4Fe + 6CO_2}[/tex]
2 moles of Iron oxide produce, 4 moles of iron hence the molar ratio is 1:2.
Molar mass of Fe = 55.85 g/m
Molar mass of iron (III) oxide = 159.7 g/mol.
Moles of iron oxide,
[tex]\bold {\dfrac w{m} = \dfrac {3.80\ g}{159.7\ g/mole} = 0.0237\ moles }\\[/tex]
So, moles of the iron,
[tex]\bold {0.0237\ moles \times 2 = 0.0475\ moles}[/tex]
Molar mass of Fe = 55.85 g/m
Thus, mass of iron,
[tex]\bold {w = n\times m = 55.85 g/mol \times 0.0475 m = 2.66 g}[/tex]
Therefore, the mass of iron obtained from 3.08 g of iron(III) oxide is 2.66 g.
