Empirical Formula & Molecular Formula Determination From Percent Composition
Рет қаралды 3,574,233
Күн бұрынThis chemistry video tutorial explains how to find the empirical formula given the mass in grams or from the percent composition of each element in a compound. If you're given the mass percent, you can simply treat it as if you were given the mass in grams. This video explains how to find the molecular formula given the molar mass of the compound. You can do this once you have the empirical formula. This video explains all of it. It has plenty of practice problems and examples for you to master this lesson.

Professor Organic Chemistry Tutor, thank you for using examples to Compute the Empirical and Molecular Formula in AP/General Chemistry. The simplest (empirical) formula of a compound gives the simplest whole number ratio between the number of atoms of different elements in a compound. The molecular formula indicates the number of atoms of each type in a molecule. This is how Chemistry books breakdown the material presented in the video. This is an error free video/lecture on KZfaq TV with the Organic Chemistry Tutor.
