When you make the Carbon Dioxide with the reaction, there was already regular air in the bottle and the tube, so wouldn't it be Carbon Dioxide, water vapor and nitrogen and whatever else was in the regular air in the graduated cylinder? I don't understand how you can calculate for just water vapor and carbon dioxide. Were you simplifying things, or was there some way you didn't get any of the regular air in the graduated cylinder?

Please don't tell me I was the only one with a calculator during his calculation of oxygen's pressure in air and concluded with a 19. 278 KPa which can be rounded to 20 NOT 21 KPa!

1: 23 This is where you lost me. Does this mean that after they mingle the total pressure in the room will be the same as each individual room before the rooms mixed?

Why did he measured he CO2 level again? And how did he got to know about the atmospheric pressure by knowing the volume? Anyone there who can help me out with this.

You need to wait for the CO2 to completely displace the air left in the plastic bottle before placing the tube under the graduated cylinder.

How does he have an oxygen tank when he lives in Montanna? That's where you live right? I love your videos! Keep doing your thing!
