QUESTION:

One of the reactions that occurs in a blast furnace, where iron ore is converted to cast iron, is

                 \(\mathrm{Fe}_{2} \mathrm{O}_{3}+3 \mathrm{CO} \longrightarrow 2 \mathrm{Fe}+3 \mathrm{CO}_{2}\)

Suppose that \(1.64\times10^3\mathrm{\ kg}\) of \(\mathrm{Fe}\) are obtained from a \(2.62 \times 10^{3}-\mathrm{kg}\) sample of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\). Assuming that the reaction goes to completion, what is the percent purity of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) in the original sample?

Assuming that the reaction goes to completion, what is the percent purity of \(\mathrm{Fe}_{2} \mathrm{O}_{3}\) in the original sample?

ANSWER:

Step 1 of 3

Here, we are going to find out the purity % of  in the original sample.

The given balanced chemical reaction is as follows.

From the above balanced chemical equation  one mole  produce two moles of Fe.
