Chemistry 10-29-13 Moles, Mass, Atoms & Avogadro

CHEMISTRY: So… how big a bucket do you think we’d need to hold a mole of frogs? πŸ™‚ Nope, not the furry brown creature that burrows underground, it’s a whole different thing! Here’s the lecture from Tuesday on moles, mass, and Avogadro’s number. I still say he has a cool name…

Chemistry 11-2-11 Moles, Mass & Molecules

CHEMISTRY: So how many water molecules are in that drop? Here’s the lecture from today on using molar mass as a conversion factor. You did a great job on the problems! Keep practicing them so you don’t forget!

By the way, were you ready for a quiz today? What about tomorrow? Don’t give up – keep working on memorizing polyatomic ions, acids, and the chemical names for those common substances you researched. Have you tried making a song?

Chemistry 10-31-11 Moles, Mass, Atoms Problems Practice

CHEMISTRY – So, how big a bucket do you think we’d need for a mole of candy corn? Yum! πŸ™‚ Here’s the short review we did on the mole, mass, atoms problems. Did it help? Just don’t forget the conversion factor, and think through the problems. Put units first and then numbers. Make sure what you’re doing has a reason and makes sense!

Hon Chemistry 10-18-11 Using Chemical Formulas – Moles & Mass

HON CHEMISTRY: Good job using chemical formulas as tools today! So it turns out there are tons of ways that you can use them. Like finding molar mass, moles, and molecules! Did it all sound familiar to you – like we were repeating yesterday’s lecture? Here’s the lecture from Tuesday.

Hon Chemistry 10-17-11 Moles, Molar Mass & Avogadro’s Number

HON CHEMISTRY: Hey guys, here’s the lecture from Monday on moles, molar mass, and Avogadro’s number. 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………
