Chemistry 10-29-18 Intro to Chemical Names & Formulas

CHEMISTRY: Great job learning to name binary ionic compounds – and even beginning to write formulas! Tomorrow let’s add polyatomic ions! Whoot, whoot!!

Speaking of formulas, what is your plan for all the memorization in this chapter? Word of warning – don’t wait to the last minute!!

Super important – the secret for the next few days and this entire chapter is DON’T GET BEHIND! Keep up with me and practice, practice, practice!

Hon Chemistry 10-29-18 Moles, Molar Mass & Avogadro’s Number

HON CHEMISTRY: So….you think if his work helped us understand something as significant as the number of something in a mole they might name something after him? They did! Go figure! Another name for the number of anything in a mole is Avogadro’s Number. That would be how many?

You caught on super fast today! Remember, it’s all in terms of one mole. The mass of one mole, the molar mass, is the average atomic mass of the element in grams (periodic table). And the number of atoms in one mole is …. well you know that. Speaking of moles, isn’t he cute? Well, beauty being in the eye of the beholder and all. Hmmmm………
