Answer : The correct option is, (b) 22.1 g
Solution : Given,
Mass of iron = 15.5 g
Molar mass of iron = 56 g/mole
Molar mass of = 160 g/mole
First we have to calculate the moles of iron.
Now we have to calculate the moles of .
The balanced reaction is,
From the balanced reaction, we conclude that
As, 2 moles of iron obtained from 1 mole of
So, 0.276 moles of iron obtained from mole of
Now we have to calculate the mass of
Therefore, the amount of required are, 22.1 grams.
