Question

FeS2 + 5 O2 2Fe2 + 4SO2 How many moles of FeO are formed from 0.57 moles of O2?

Answer 1

Answer:

0.228 mol FeO

Explanation:

                                 2FeS2 + 5 O2----> 2FeO + 4SO2

from reaction                           5 mol       2 mol

given                                       0.57 mol    x

x = 0.57*2/5 = 0.228 mol FeO
