6.82 moles of Fe2O3

Explanation:

Step 1:

Determination of the number of mole of in 450g of CO2.

This is illustrated below:

Molar Mass of CO2 = 12 + (2x16) = 44g/mol

Mass of CO2 = 450g

Number of mole of CO2 =.?

Number of mole = Mass/Molar Mass

Number of mole of CO2 = 450/44 = 10.23 moles

Step 2:

Determination of the number of mole of Fe2O3 needed for the reaction. This is illustrated below:

2Fe2O3 + 3C—> 4Fe + 3CO2

From the balanced equation above,

2 moles of Fe2O3 reacted to produce 3 moles of CO2.

Therefore, Xmol of Fe2O3 will react to produce 10.23 moles of CO2 i.e

Xmol of Fe2O3 = (2x10.23)/3

Xmol of Fe2O3 = 6.82 moles

Therefore, 6.82 moles of Fe2O3 is required.
