Chemistry 11-15-11 Empirical Formulas

CHEMISTRY: So, would you like to be Greg on CSI? Great start on empirical formulas today. 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. And don’t forget the little step you might have to add to the end. Tomorrow – molecular formulas! πŸ™‚
