Practice Problem: Empirical and Molecular Formulas

How do we know how many atoms of each element are in a particular compound? Through clever experiments! Here let's practice using percent mass information to get the empirical and molecular formulas of a particular compound.

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

Hi, Professor Dave! I really love your videos. Its easy to understand. Can I use this as a reference to my class? Thanks in advance! :)

about the nicotine problem, you can also just assume its 100 grams because the weight is given as a percentage and still get the right answer :D (if its just the Empirical Formula)

Can you do a video on predicting precipitation- Ksp and ionic product calculations please

Should've explained the Molecular part better.

thanks for the great practice problem man, appreciate it

You keep saying "atomic mass", I think you mean "molar mass", right?

should i still email you given that you probably have 5000+ emails that r unread
