Here is a video I found explaining the road map: http://m.youtube.com/watch?v=mBVL0PHPrhg

Moles and Molar Mass
The past two days we have gotten started on our new unit. The first day we focused on what a mole is, that being a quantity of measurement and shown as 6.02x 10^23 representative particles. We have walked through the steps of converting between grams, volume, and mass, ultimately with moles in the middle of this action. Here is the chart that will show this process. You use this chart as essentially conversion factors to get to where you want. On the second day we were introduced to this process with compounds rather than just one element. The difference with that process is that the atomic mass must me multiplied by the amount there are. For example, C3H8 would have to multiple the atomic mass of carbon by 3 and hydrogen by 8.

Thanks for this post it is very helpful. I like how you put the road map on your post. Also the YouTube video is very helpful.
ReplyDeleteHolly, I liked how you explained how the mole road map works in depth and the difference in atomic mass between elements and compounds. Also, your video was very helpful and explained the volume side of the mole map that we have not used in class. However, maybe consider showing an example of how the road map works by posting an example with conversions next time. This could be very handy for someone who doesn't understand the concept. Other than that, your post was great!
