Determine the percentage by mass of oxygen and Sb in the compound, `Sb_(2)O_(5).[Sb=121.77]`.

Text Solution

Verified by Experts

Molecular mass of
`Sb_(2)O_(5)=2xx121.77+5xx16=323.54`
`therefore`Atomic of oxygen present `=(5xx16)/(323.54)xx100=24.73%`
Amount of Sb-present`=(2x121.77)/(323.54)xx100=75.27%`.
