Answer : The mass of iron needed is 29.5 grams.
Explanation : Given,
Mass of = 12 g
Molar mass of = 32 g/mol
First we have to calculate the moles of .
Now we have to calculate the moles of
The balanced chemical equation is:
From the reaction, we conclude that
As, 3 moles of react with 4 moles of
So, 0.375 mole of react with
mole of
Now we have to calculate the mass of
Molar mass of = 59 g/mole
Therefore, the mass of iron needed is 29.5 grams.
