" Iron oxide has formula "Fe_(0.94)" O.What fraction of Fe exists as "Fe^(-3)" ? "

From analysis it is found that iron oxide has the formula Fe_(0.95)O_(1.00) . What fractions of iron exist as Fe^(2+) & Fe^(3+) ions.

The non - stoichiometric iron oxide has a composition Fe_(0.94) O . Find the ratio of ferrous and ferric ions present in it.

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?

A sample of ferrous oxide has actual formula Fe_(0.93)O_(1.00) . In this sample what fraction of metal ions are Fe^(2+) ions? What type of non-stoichiometric defect is present in this sample?

A sample of ferrous oxide has actual formula Fe_(0.93)O_(1..00) . In this sample what fraction of metal ions are Fe^(2+) ions? What type of non-stoichiometric defect is present in this sample ?
