If by "air" you mean oxygen, then the mole ratio can by found by balancing a reaction equation. CH4 + 202 -> CO2 + 2H2O The ratio is 1:2.
1.7 kg air is required to burn 1 kg of nitromethane. AFR = 1.7
Methane gas settles down because methane gas is heavier than and is carried by the upward displacement of air. ---------------------------------------------- The density of methane is 0,717 g/L and the density of air is 1,2 g/L at 0 0C; consequently methane gas raise in the air.
CH4 + 2 O2 --> CO2 + 2 H2Ox / 64 = 1 / 16x = 4 g oxygenAssuming oxygen is 20% oxygen...4 = .2 xx = 20 g air that is one possible answer.A better answer--- air is 20% oxygen by volume and 80% nitrogen by volume.1g methane / 16 = 0.0625 mole0.0625 / 1mole meth = x / 2mole oxyx = 0.125 mole oxygen =20% of air--- 0.625 mole 'air'0.2 x 32 + 0.8 x 28 = 28.8 g/mole of air0.625 x 28.8 = 18 grams of airSince air is 20% oxygen by volume, the 2nd answer is best.
the percentage of these three gases in the air is as follows: Methane: 0.00002% Krypton: 0.00011% Hydrogen: 0.00005%
Yes, but it is very dangerous to the human body, in that high enough concentrations in the air can result result in suffocation.

Yes methane is lighter than air because it is less dense than air.
The fact that it oxidizes in air is a chemical property of methane.
The main reason is that oxygen is abundant in the atmosphere but methane is not. Air is 21% oxygen but only 0.00018% methane, so there is not enough methane in air to be of any use.
Flatulence contains a portion of methane gas, and the methane portion is lighter than air.
