HON CHEMISTRY: I was really impressed today with the progress you’ve made on mastering percent composition and empirical formulas! Now it’s time to move on to molecular formulas!
Remember what molecular formulas are – just a multiple of the empirical formula. Keep that concept in mind, and you’ll have no problem remembering to divide the molecular formula mass by the empirical formula mass to find X! Easy peasy!
Are you starting to catch on to the steps? It will be good for you to memorize them, but would it not be just tons better to understand why you need each step – backwards and forwards, so then you wouldn’t need to memorize them at all!
Need some extra practice? Help Session next Tuesday morning, 7:15ish A.M.
