An organic compound contains 69% carbon ...

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.

Text Solution

Verified by Experts

precentage of `C=(12)/(44)xx("mass of "CO_2" formed")/("mass of substance taken")xx100`
`4.8=(2)/(18)xx("mass of "H_2O" formed")/("mass of substance taken")xx100`
or mass of water found `=(4.8xx18xx0.2)/(2xx100)=0.0864gm`
