Question

Equivalent weight of FeC20 in the change: FeC20 ---------Fe3+ +C02

Answer 1

By mistake you typed FeCO .
Here
FeC2O4 →Fe^+3 + 2CO2 + 3e
We know
Change in oxidation state = ±3
So,
equivalent weight = molecular weight/3
= ( 56 + 24 + 64)/3
= 144/3 =48 u

Answer 2

Answer:is m by 3

Explanation: Its becoz in this equation fe changes by 3 and there is no change in the oxidation no. Of fec2o4 to co2

Hence frm the formula of equialent weight which is M by change we get M by 3!.
