The mixture of hydrogen, methane and co gases under normal conditions has a density of 0.857g per dm3. 4.52 volumes of air are required for complete combustion of one volume of the mixture. Determine the composition of the mixture in percent. Can someone help me i know to write reactions but what ne...

OK, but what with other steps

1. Calculate density of CH4, H2 and CO at normal conditions (T = 20 C, p = 1 atm). 2. If mixture composes of 100 % CH4 it will have density you have calculated. If 100 % H2 - some other density. If 100 % CO - yet another density. 3. Calculate how many litres of air is needed to burn 1 litre of pure ...
