A hydrocarbon burns in air[oxygen] giving 0.36g.water vapour and 0.44 g of carbon dioxide as the only products.If the weight of hydrocarbon is 0.16g, show that the results are in acccordance with- law of conservation of mass.[h=1,c=12,o=16]

Answer 1

there would have 5 molecules of that hydrocarbon
