Question

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

Answer 1

Hey mate!

Here's your answer!!

We will try to do it step by step.......

Percentage of hydrogen in organic compound is 4.8.

∴0.2 g of organic compound will contain = 4.8 x 0.2/100 = 0.0096 g of H

Molecular mass of water (H2O) is 18 g.

∴0.0096 g of hydrogen will be contained
= 18 × 0.0096/2 = 0.864 g of water

Thus, 0.0864 g of water will be produced on complete combustion of 0.20 g of the organic compound.
