Mr KCl | = | Ar K + Ar Cl |
= | 39 + 35 | |
= | 74 |
mol KCl | = | gram KCl Mr KCl |
= | 100 74 | |
= | 1,35 |
jumlah molekul KCl | = | mol KCl x bilangan Avogadro |
= | 1,35 x 6,02 x 1023 | |
= | 8,127 x 1023 |
jumlah atom K | = | jumlah atom K dalam KCl x jumlah molekul KCl |
= | 1 x 8,127 x 1023 | |
= | 8,127 x 1023 |
Jumlah atom K | = | 8,127 x 1023 |
