Question

What mass of CO is required to react with 25.13g of Fe₂O₃ according to the equation

\(F{e_2}{O_3} + CO \to 2Fe + 3C{O_2}\)

Short answer

13.22g of CO is required to react with 25.13 g of Fe₂O_3.

Step-by-step solution

Calculating the number of moles of CO

From the given balanced reaction, we can say that 1 mol of Fe₂O₃ produces 3 mol of CO.

n=Moles of Fe₂O₃

= mass present/Molecular weight

=25.13g/159.69g

=0.1574 mol

Then the number of moles of CO

= 3 times the moles of Fe₂O₃

= 3 x 0.1574mol

=0.4721 mol

Calculating the mass of CO

For calculating the mass, we use the formula of moles n = m/M. So,

m=M.n

=28.01 g x 0.4721 mol

= 13.22 g of CO
