Answer:
234.68g
Explanation:
We understood from Avogadro's hypothesis that 1mole of any substance contains 6.02x10^23 atoms. Therefore, 1mole of Fe2O3 also contains 6.02x10^23 atoms
1 mole of Fe2O3 = (56x2) + (16x3) = 112 + 48 = 160g
Now, if 160g of Fe2O3 contains 6.02x10^23 atoms,
Therefore Xg of Fe2O3 will contain 8.83×10^23 atoms i.e
Xg of Fe2O3 = (160x8.83×10^23)/6.02x10^23 = 234.68g
