The weight percentage of carbon dioxide and carbon disulphide are respectively `27.27% and 15.79%`. What is the composition of oxide of sulphur, if the weight percentage of oxygen is 50?

Explanation

Weight of Oxygen that combines with 1 g of
Carbon `=(72.73)/(27.27)=2.67g`
Weight of Sulphur that combines with 1 g of Carbon
`=(84.21)/(15.79)=5.33g`
Ratio of weight of S and O that can combin with same weight of carbon is `5.33:2.67=2:1`
The simple multiple ratio is `1:1`
The oxide is sulphur dioxide, `SO_(2)`
