Experimentally it was found that a metal oxide has formula M_(0.98)O.Metal M^(2+) and M^(3+)is present as M^(3+)in its oxide. Fraction of the metal which exists as M^(3+) would be

Experimentally it was found that a metal oxide has formula M_(0.98)O.M

1.	Experimentally it was found that a metal oxide has formula M_(0.98)O.Metal M^(2+) and M^(3+)is present as M^(3+)in its oxide. Fraction of the metal which exists as M^(3+) would be
Answer» `6.05%` `5.08%` `7.01%` `4.08%` SOLUTION : `2X +(98-x)3=200` `M^(2+)=x=93.02%` `M^(3+)=4.08%`
