Question
What mass of CO is required to react with 25.13g of Fe2O3 according to the equation
\(F{e_2}{O_3} + CO \to 2Fe + 3C{O_2}\)
Step-by-Step Solution
Verified Answer
13.22g of CO is required to react with 25.13 g of Fe2O3.
1Calculating 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
2Calculating 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
