The actual formula derived from the analysis of a sample of ferrous oxide is Fe_(0.93)O_(1.00) . What fraction of iron in this sample does exist in the form of Fe^(2+) ions?

Analyses shows that FeO has a non-stoichiometric composition with formula Fe_(0.95)O_(1.00) . Give reason.

The non- stoichiometric compound Fe_(0.94)O is formed when x% of Fe^(2+) ions are replaced by as many 2//3 Fe^(3+) ions The value of x is:

Analysis shows that FeO has a non-stoichiometric composition with formula Fe_(0.95)O . Give reason.
