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.

I love the practice videos!

[@LOKESHTHIMMANA]

Thank you... Dea ... Dave

[@li-annlavina666]

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! :)

[@awabtech5694]

mr dave thx man these was so help ful

[@benlevi97]

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)

[@nantoubojang1129]

You are indeed a genius

[@WyattFoster-po7st]

Thanks

[@kamiiz1290]

Should've explained the Molecular part better.

[@nimapourjafar3701]

thanks for the great practice problem man, appreciate it

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

[@ProfessorDaveExplains]

that's coming!

[@daphodil241]

Professor Dave Explains thank you, patiently waiting

[@SaeedNeamati]

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

[@ProfessorDaveExplains]

Atomic mass is in amu, molar mass is in g/mol.

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