Free webinar on Robotics (Block Chain) Learn to create a Robotic Device Using Arduino
30th Jan @ 5:00PM for Grade 1 to 10
A mixture of FeO and Fe2O3 is reacted with acidified KMnO4 solution (0.22M and 100ml was used), the solution then was treated with zinc dust which converted all the Fe+3 to Fe+2 ion this Fe+2 require 1000ml of 0.13M K2Cr2O7 solution. Find the mass % of Feo and Fe2O3.

Find the mass % of Feo and Fe2O3.
mass % of FeO = (moles of FeO * mass of FeO) / ((moles of FeO * mass of FeO) + (moles of Fe2O3 * molarmass ))= 6.92%
