# what is the conversion factor of Fe in Fe2O3?how to find conversion factor?give one example.thanks?

Relevance

Molar mass Fe = 55.84g/mol

Fe2 = 55.84*2 = 111.68

Molar mass Fe2O3 = 159.69g/mol

Conversion factor = 111.68/159.69 = 0.699

The conversion factor is 0.699 ( you could most probably happily work with 0.7

Using Example: Mass of Fe2O3 in sample = 57.4g

Mass of Fe in sample = 57.4*0.7 = 40.18g

• You can have several conversion factors

1 Fe2O3 molecules = 2 atoms Fe

1 mole Fe2O3 = 2 moles Fe

160 g Fe2O3 = 112 g Fe

• All you need to do, is apply the conversion factor. The conversion factor for Fe2O3 is 1.4298

element percent = oxide percent /conversion factor

or

Assuming you know the element percent and you need to convert it the oxide percent,

then, oxide percent = element percent x conversion factor
