Moles of methane. No half molecules, I think!
2.50 moles methane (1 mole C/1 mole CH4)(6.022 X 1023/1 mole C)
= 1.51 X 1024 molecules of carbon

One RBC contains about 250 million Hemoglobin molecules
It's a mixture of hydrogen, carbon and other 'trace' elements. Natural gas is a naturally occurring hydrocarbon gas mixture consisting primarily of methane, but commonly including varying amounts of other higher alkanes, and sometimes a small percentage of carbon dioxide, nitrogen, hydrogen sulfide, or helium. All is removed from the methane before it is used. We have from 250-100 years of natural gas left depending of the amount of usage.
250 of them.
1.88 X 1024 molecules SO3 (1 mole SO3/6.022 X 1023)(80.07 grams/1 mole SO3) = 250 grams sulfur trioxide ===================
Yes, the atmosphere is changing, and especially in the last 250 years since the Industrial Revolution.Pollution from human activity is changing the atmosphere.Burning of fossil fuels (coal, oil and natural gas) in industry, transport and the generation of electricity, which releases carbon dioxide (CO2).Bad agricultural practices emit methane (CH4), a powerful greenhouse gas.Deforestation has removed the trees that used to take carbon dioxide from the atmosphere.
