An organic compound contains 69% carbon and 4.8% hydrogen, the remainder being oxygen. Calculate the masses of carbon dioxide and water produced when 0.20 g of this substance is subjected to complete combustion.

Explanation

Ammount of C in 0.2g of compound= `0.2 xx 69/100 = 0.138g`
Now, `C equiv CO_(2)`
12 g of carbon gives `44/12xx0.138g = 0.506g`
Ammount of H in 0.2 g ofcompounf= `0.2xx4.8/100=0.0096g`
Now `2H equiv H_(2)O`
2g of hydrogen gives 18g water on combustion.
`:.` 0.096g of hydrogen gives `18/2 xx0.0096 0.0864g`
