Atoms are so tiny; it is practically impossible to hold them with any instrument. So how is the mass of a single atom calculated then? Watch this video which gets us introduced to the interesting concept of Atomic Mass.
In this video, we will learn:
0:00 How do we calculate the mass of a single atom?
1:50 Calculating mass of an atom wrt a carbon atom
2:41 One atomic mass unit
3:56 What exactly gives the atom its mass?
This 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.
This chemistry video tutorial provides an introduction to moles. It explains the concept of moles and how it relates to mass in grams by the molar mass of a compound. It also explains how moles relate to atoms and molecules through Avogadro's number.
This chemistry video tutorial explains the conversion process of moles to atoms and how to convert the number of atoms to moles. This tutorial contains plenty of examples and practice problems. This tutorial is useful for calculating stoichiometry problems.
In this education video by The Fuse School, you are going to learn about:
- How to calculate Relative Atomic Mass
- How to calculate Relative Atomic Mass for different elements
- Calculating total mass number of isotopes
