The answer depends on what the pressure is.
I think it is 0.1227 pounds but I have seen 0.1144 pounds used.
Carbon dioxide is a naturally occurring compound in the atmosphere. Total amount has to be in the trillions of pounds. There is a more in depth answer at the link below.
Burning one pound of carbon releases about 3.6 pounds of carbon dioxide (the extra weight comes from oxygen from the air).

Assuming that coal is essentially pure carbon, each 12 kg of coal will combust to form 44 kg of carbon dioxide (C+O2 -->CO2) a bit more than 3 times as much carbon dioxide as coal. A ton of carbon will burn to form about 3 tones of carbon dioxide.
We produce 1.37 pounds of carbon dioxide with every kilowatt of energy consumed.
On average, trees absorb about 48 pounds of carbon dioxide per year. This can vary depending on the species, age, and size of the tree. Working to protect and plant trees is important in mitigating climate change by capturing carbon dioxide from the atmosphere.
10 pounds of coal consists of carbon and other elements that combine with oxygen during combustion to produce emissions such as carbon dioxide, sulfur dioxide, and nitrogen oxides, as well as leftover ash. The chemical reactions that occur during combustion result in the transformation of the coal's elemental composition into emissions and ash.
The amount of carbon dioxide produced by a gas stove depends on the type of fuel used and the efficiency of the stove. Burning 1 cubic foot of natural gas typically produces about 12 pounds of carbon dioxide. However, newer stoves are more efficient and produce less carbon dioxide compared to older models.
Although aviation is a relatively small industry, it has a disproportionately large impact on the climate system. It presently accounts for 4-9% of the total climate change impact of human activity.
800 pounds of water would be 95.8 US gallons.
42 gallons of water is 350.7 pounds
