Question

How many moles of Fe are obtained from 1 mole of Fe2O3

Answer 1

HELLO MATE

In one mole of fe2o3 there are two moles of iron atoms. Now gram atomic wt.of Fe is 56.So in one mole of Fe2O3 there are 2×56=112 gm of Fe. Hence in 1.75moles Fe2O3 there are 1.75×2 moles or 1.75×56 gm of iron.

Answer 2

$\huge\red{Hello there !}$

____________

How many moles of Fe are obtained from one mole of Fe2O3 ????

Its simple , first of all write balanced equation

$\huge\pink{Balanced equation }$

2Fe2O3 ---------> 4Fe + 3O2

This balanced equation shows that

2 moles of Fe will produce 4 moles of Fe

then .....

1 mole of Fe2O3 will produce 2 moles of Fe

2 mole Fe2O3 = 4 mole Fe

1 mole Fe2O3 = 4/2 mole of Fe

$\huge\blue{1 mole Fe2O3 = 2mole of Fe }$
