CHEMISTRY: So, would you like to be Greg on CSI? I missed you guys on Friday! Here’s the lecture you watched today on calculating empirical and molecular formulas.

The hardest part is that it’s not a set formula for you to plug and play, but if you’ll keep in mind that you’re really just looking for subscripts which are just moles, you’ll be able to think it through. Percent to mass, mass to moles, moles to smallest whole number ratio. Simple! 🙂
