Avogadro's Number How To

[211183]

When do you know why you multiply or divide by Avogadro. I am realizing about 5 topics I just skipped because I didn't like them.... hah

basically when you want the # of particles or the moles of something.

Avogadros number is #atoms per mol so its more of a cancellation of units kinda thing.

ok this is how i look at it.... if your mom asks u how many eggs are in the frig u wont say 524.654 right? cuz that doesnt make sense. Avogadro's Number works the same way... its when you want to COUNT the number of electrons, hydrogens, OH's, C's, donkeys, monkeys, hats or whatever lol

so its for when u count and a keyword to keep in mind when u see a question is NUMBER

hope that helped
