Question

If you need to produce 9.75 moles of iron(III) oxide (Fe2O3), how many moles of iron will be required? *

Answer 1

Answer: Thus 9.75 moles of iron will be required.

Step-by-step explanation:

The balanced chemical reaction is:

`2Fe+3O_2\rightarrow 2Fe_2O_3`

According to stoichiometry :

2 moles of
`Fe_2O_3` are produced by= 2 moles of
`Fe`

Thus 9.75 moles of
`Fe_2O_3` are produced by=
`(2)/(2)* 9.75=9.75moles` of
`Fe`

Thus 9.75 moles of iron will be required.
