Answer:
2.11 %
Explanation:
In acidic medium iron is in Fe ⁺³ oxidation state .
Equivalent weight = 56 / 3
= 18.33 gm
acid used in titration
= 16.37 mL of .0233 M
= 16.37 x .0233 mL of M soln
= .38 mL of M soln
.38 mL of M soln reacts with .3298 gm of ore
1000 mL of M soln = (.3298 / .38) x 1000 gm of iron ore
867.89 gm
This must contain one gm equivalent of iron
or 18.33 gm
867.89 gm of ore contains 18.33 gm of iron
mass % of iron in the given ore
= (18.33 / 867.89) x 100
= 2.11 %
