Even more mole conversions!!!

Last class we worked on the simpler mole conversions
- only going from mole to particle and reverse, and gram to mole and reverse

But!!! today we did harder mole conversions
- we went from particles to mass and reversed
(that means we had to convert through moles) yikes!!

The very first thing you need to know about harder mole conversions is the MOLE MAP!!
it's very helpful!!!

MM= molar mass
in each box all the top amounts are divided by the bottom amounts
With this tool you can go through any conversions using moles!!

Here is a video simplifying mole conversions
Mole conversions made easy :)

Whenever your doing Mole conversions NEVER forget AVOGADRO'S number
(6.022x 10 ^23)

This is what we learned today and next class we have a quiz!!
If you want to try some practice questions here is a link to ms. Chens website
