What is the percent by mass of titanium in rutile, a mineral that contain Titanium and oxygen, if structure can be described as a closet packed array of oxide ions, with titanium in one half of the octahedral holes. What is the oxidation number of titanium ?

Explanation

`O^(2–)=(1)/(8)xx8+(1)/(2)×6=4`
`Ti(l+12xx1//4)/(2)=(4)/(2)=2`
`TiO_(2)` formula
Ti(At mass)=47.88
`%Ti=(47.88)/(79.88)xx100=59.94%`
Ox. State= +4
