Here’s my plan. Any criticism is welcome.

I'm going to make co2 by combining baking soda and citric acid together in a plastic bag that is sealed to a hose/tube that feeds into a face mask. This is the only method available to me right now.

Concentrations of more than 10% carbon dioxide may cause convulsions, coma, and death [1, 15]. CO2​ levels of more than 30% act rapidly leading to loss of consciousness in seconds. This would explain why victims of accidental intoxications often do not act to resolve the situation (open a door, etc.)

this might be a good method actually
what about mixing 1kg baking soda and 1kg citric acid in a bath with all the door and windows sealed with tape

Thank you. This sounds quite easy to set up, and peaceful. I wonder how long one must be breathing inside the room for it to be successful.

I've heard to let the gas build up before breathing it in, so that there's less discomfort and it will get the job done quicker. Im inept at all this. Just sharing what I've read about it.

It makes sense to have an initial build up, and perhaps a second batch to make sure it's enough.

width*length*height
8,988,750,000,000,000,000,000,000,000 nm room space
602,000,000,000,000,000,000,000 one mole

need 14,931 moles of co2 to have 100 percent room filled with co2
need 4479 moles to have room filled with 30 percent co2
need 1493 moles to have room filled with 10 percent co2

That is for every 1 gram of citric acid use 1.3 g of baking soda. This will give you the maximum amount of CO2. Then, for example, if you use, say, 25 g of citric then mix that with 32.8 g of baking soda . This will generate 0.39 moles of CO2 or 0.39 moles X 44g/mol = 17.2g of CO2 gas.

a 1kg of baking soda is capable of producing 11.7 moles of co2
98.4grams of baking soda to 75gram citric acid procedures 1.17 moles of co2

1493 moles would be needed for 10 percent co2 concentration
1493\11.7=127.60

would need 127kg baking soda to fill the bath room up with 10 percent co2 levels

Thats an awful lot of baking soda! 279 pounds of it. And thats only for 10% concentration, not even for 30%.
Also I thought there's a lot of body panic with CO2. There isnt supposed to be panic or pain with CO.

I'm slightly concerned about the hyperventilating feeling but not enough to not try.

Thank you forthe math. So much for this method. It was too good to be true. The bag over your head doesn't do it for me. Too bad.
