Density of Gases

Great technique for measuring the mass of different gases, comparing their densities, and determining their molar masses.

studying chem was really boring but this dude impresses me everytime would like to take a full chem class from him

[@desireedaniels42]

Wow learned a lot for 13 mins and 39 second. thanks professor.....

[@jimlee5626]

Thanks! Sipping coffee on a Sunday morning and you helped me learn a bit. Cheers!

I need info on co truck exhaust fume. I need info if those gases are going up or staying in the bottom of semi truck. I want to see which direction I install a fan from top cab window in or out to have fresh air?

On the chalkboard is written: Mass of 54.9mL. I think it should read VOLUME of 54.9 mL. Right? In the video the instructor says VOLUME of 54.9 mL. Right?

Thank you sir You explain me yery nicely

clear !!!

Thanks Sir!😁

My man, I have a sort of silly question. How does gravity affect mass - namely, the gravity of the planet earth and Zero gravity against the mass of gases. To determine the safety of "air" in Zero gravity and/or how long the safety would last.

[@loppol6035]

Uh I don’t think gravity can affect mass,it’s mass that affects gravity
