Answer:
1.29 moles of carbon dioxide can be produced.
Explanation:
1st) It is necessary to convert 68g of Fe2O3 into moles, by using the molar mass of Fe2O3 (159.7g/mol):
[tex]68g*\frac{1mole}{159.7g}=0.43moles[/tex]Now we know that 68g of Fe2O3 are equal to 0.43moles.
2nd) From the balanced equation we know that 3 moles of carbon dioxide (CO2) are produced from 1 mole of Fe2O3. With a mathematical rule of three we can calculate the moles of CO2 that will be produced from 0.43 moles of Fe2O3:
[tex]\begin{gathered} 1moleFe_2O_3-3molesCO_2 \\ 0.43moleFe_2O_3-x=\frac{0.43moleFe_2O_3*3molesCO_2}{1moleFe_2O_3} \\ x=1.29molesCO_2 \end{gathered}[/tex]So, 1.29 moles of carbon dioxide can be produced.
