I have discussed Introductory Organic Formula Naming / Writing on 5/21/2014 with posts related to Organic Chemistry.
When teaching this topic, it is typical to address it briefly along with the Ionic Formula work.
FYI, using Percent Composition Data to Determining a Formula was addressed on 2/26/2014.
Here is a longer video (18 minutes) about Molecular Formulas (it's very comprehensive):
Here are a few worksheets focusing on Binary Molecular Formula Naming / Writing

Buy my lab book "Chemistry on a Budget" -- it is available for $20 at amazon.com or $23 at lulu.com:

This book contains 13 labs using consumable materials purchased from local stores. There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
Have a good weekend and Happy Halloween!
