1. Molar Mass Practice Worksheet: Molar Mass Practice Worksheet Answer Key
Pengertian Molar Mass
Molar mass adalah massa satu mol suatu zat. Ini adalah jumlah gram suatu zat yang sama dengan massa atom atau molekulnya dalam satuan gram per mol (g/mol). Molar mass penting dalam kimia karena memungkinkan kita menghitung jumlah partikel (atom, molekul, atau ion) dalam sampel suatu zat.
Cara Menghitung Molar Mass
Untuk menghitung molar mass suatu zat, kita perlu menjumlahkan massa atom dari semua atom penyusunnya. Massa atom dapat ditemukan pada tabel periodik.
Contoh
- Glukosa (C 6H 12O 6): 6(12 g/mol) + 12(1 g/mol) + 6(16 g/mol) = 180 g/mol
- Natrium klorida (NaCl): 1(23 g/mol) + 1(35,5 g/mol) = 58,5 g/mol
Tabel Molar Mass
| Zat | Rumus Kimia | Molar Mass (g/mol) |
|---|---|---|
| Air | H2O | 18,02 |
| Karbon dioksida | CO2 | 44,01 |
| Asam klorida | HCl | 36,46 |
| Metanol | CH3OH | 32,04 |
| Glukosa | C6H12O6 | 180,16 |
