Storyboard Description

2 scientists discuss mols.

Storyboard Text

  • Dr. Mullen, do you have anything to do with these moles running around the lab?
  • Yes Dr. Scienceman, I'm using them as models for my mole conversion experiment.
  • Oh Gosh, please don't tell me you're experimenting with animal gene splicing again, I really don't want to get raided by the FBI again
  • No no no, a mole is the standard index unit of measurement for the amount of a subject, come over here, I'll show you
  • A mole represents the number 6.02*10^23, also known as avogadro's number.
  • Wow! That's a huge number, so what would, for example, a mole of water look like?
  • Well H20 is a bad example, because it's such a small molecule, a mole of h2o would be a tiny droplet, about 18ml
  • Ah that makes sense, isn't it weird that I'm a scientist but I don't have a grasp of basic chemistry?
  • I ask myself that everyday. Anyway, to convert from particles to moles, you must divide the # of particles by 6.02*10^23, to go from mass to moles, divide mass by molar mass, and from volume to mols divide volume by 22.4
  • I understand some of those words
  • Why don't we go take a break at the water cooler, I'm so thirsty I could drink a gallon water, which would be how many moles of H20 Dr. Scienceman?
  • Yes you are.
  • Let me see... According to my calculations a gallon of h20 would equal 1.265 x 10^26 moles. See, I'm not that stupid.
