Τhe mole, avogadro's number and the molar mass - تعريف المول و رقم أفوجادرو

في الفيديو ده هنتكلم عن تعريف المول و رقم افوجادرو و إزاي نحول بين المول و الوزن بالجرام
Avogadro's number is a constant that indicates the number of entities in 1 mole of this entity and it's equal to 6.022 x 10^23. For example, 1 mole of sodium contains 6.2 x 10^23 atoms of sodium. In this video, we will explain the concept of Avogadro's number and the mole and how to use them to calculate the amounts in grams and how to do the inter-conversions between them all.
