konsep mol
Pengertian mol
Mol merupakan jumlah tertentu untuk menyatakan banyaknya suatu zat yang berukuran mikroskopis (berukuran kecil). Satu mol menunjukkan banyaknya partikel yang terkandung dalam suatu zat yang jumlahnya sama dengan jumlah partikel dalam 12 gram atom C-12.Satu mol materi merupakan penyederhanaan jumlah partikel suatu ion, molekul, maupun unsur

Bilangan Avogadro
bilangan Avogadro = L = 6,02 x 1023
5
Hubungan mol dengan jumlah partikel dan bilangan Avogadro
1 mol = 1 x bilangan Avogadro =1 mol x 6,02 x 1023 partikel/mol
= 6,02 x 1023 partikel
mol = jumlah partikel / bilangan Avogadro
contoh :
9,03 x 1022 partikel = 9,03 x 1022 partikel/ 6,02 . 1023 partikel/mol
= 1,5 x 10-1 mol
6
Kesimpulan
mol adalah satuan hitung yang digunakan dalam ilmu kimia untuk mempelajari tentang materi yang memiliki ukuran partikel sangat kecil
