Mass and moles of an element

Mass and moles of an element - Chemistry Form 4: Chapter 3 - Mass and Moles of an element.

Molar mass is the weight of one mole of any chemical compounds.
Molar mass ==> Relative Molecular Mass

Hopefully this Mass and moles of an element works! Study smart.

Understanding of Mole concept

Understanding of Mole concept - The next chapter for Chemistry Form 4 is Chapter 3 about The Mole.

There are 2 important point that you need to know:

• A mole is the quantity of anything that has the same number of particles found in 12.000 grams of carbon-12. That number of particles is Avogadro's Number, which is roughly 6.02x1023
• A mole of carbon atoms is 6.02x1023 carbon atoms.

The image below for detail and understand technique as well as core concept for Mole, so please imagine and save it in your memory:



More picture about Mole concept and activity:


Description: Figure 5-2. One mole of sulfur (a), potassium dichromate (b), and graphite (c) has a mass in grams which equals the mass of a single particle of each substance. Each amount shown here contains 6.02 x 10(23) particles for that substance.
