HON CHEMISTRY: Awesome job today!! You conquered percent composition and then turned it around to find empirical formulas.e
Be sure and practice – especially empirical formulas! If you don’t it’ll get all turned around and you’ll end up leaving off an important step. 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. Easy peasy!
I wonder what the percent composition of bubble gum is?
