16 g. methane is one mole, so 2 moles of O2 are required for perfect combustion.

Since the atomic mass of carbon is approximately 12 and the atomic mass of hydrogen is approximately 1, the molar mass of methane is 16 g/mole. Therefore according to this equation it will take two moles of oxygen gas to burn the methane but since it exists in nature only as O2 then it will take 4 moles of oxygen to complete the reaction.

In the reaction of the burning of methane producing CO2 and H2O 1 mole of CH4 is burned. (carbon weighs12 and 4 H's at one each)(16g)
CH4 + 2O2 ---> CO2 + 2H20, first balance the equation.
It shows that for every mole of CH4 burned it takes 2 moles of O2

2 moles of O2

.5 L * a million mole / 22.4L * 2/a million * 22.4L / a million Stoichiometry, I kinda did it showing extra steps than mandatory you should merely multiply .5L by way of the molar ratio because of the fact that's a million:2 ratio
