You are the reason why i Understand everything ranging from bio to chemistry to math. You are the best online video tutor source period. Unfortunately, I still can't grasp the true idea behind the mole in this video. I would strongly encourage you to make another video on the mole and avogadros constant because it is soo Vital to the idea of chemistry.

Sincerely, Pat, Plus hundreds of thousands of others who are too lazy to log into their accounts on Youtube and comment on the videos.

The idea was confusing at first, but it gets very easy once you go along

I once calculated the volume of a mole of ping-pong balls. I assumed a diameter of 4 cms (I think) and got a cube of ping-pong balls whose side would stretch from Santa Cruz to Chicago. A s*** load. The sheer size of that number is staggering. Atoms are incredibly tiny.

This thing, as cheesy as it sounds and nerdy, is actually super helpful to me. My class is hella noisy, and I need to pass my Chem test tomorrow, so thankyou!!!
