In the reaction 4Fe + 3O₂ → 2Fe₂O₃, how many moles of Fe₂O₃ are formed from 12 moles of O₂? can someone please help me understand this ?

8 can solve also with ratio of moles

It's 8

O2:fe2O3, 3:2. 12:x( cross multiply). 3x:12×2.

3x:24

X:24÷3
Arifa Mujahid · 2026-06-04T19:27:00.099Z
X=8

use limiting regent trick and solve further by molar ratio ..

8 wasn't there in the options . the options were 2 , 3 , 6 and 4 moles . the statement of the question might be wrong

8 moles of Fe2O3 are formed
