) 33
O
0 46.34
38.3​

Answer 1

Answer:

Eq. Mass of Fe2O3 is 26.66 grams.

Explanation:

Eq. Mass = Mass of Substance/Valency Factor

Mass of Fe203 is 160 grams.

Valency Factor can be calculated by observing valency of Ions in a compound, i.e., 2 Fe3+ ions or 3 O2- ions in this case, Therefore valency factor = 3×2 (or 2×3) = 6

Therefore, Eq. Mass = 160/6 = 26.66
