Gram Formula Mass Calculations: Gram Formula Mass Worksheet Answers
Gram formula mass (GFM) adalah massa satu mol suatu senyawa dalam gram. Ini merupakan nilai penting dalam kimia karena memungkinkan kita untuk menentukan jumlah zat dalam suatu sampel.
Untuk menghitung GFM suatu senyawa, kita perlu mengetahui massa atom dari setiap unsur penyusunnya dan jumlah atom setiap unsur dalam rumus empiris senyawa tersebut. Massa atom dapat ditemukan pada tabel periodik.
Worksheet Format and Structure
Tabel berikut menunjukkan struktur worksheet untuk perhitungan GFM:
| Compound Name | Chemical Formula | Molar Mass (g/mol) | Gram Formula Mass (g) |
|---|---|---|---|
| Sodium chloride | NaCl | 58.44 | 58.44 |
| Water | H2O | 18.02 | 18.02 |
| Carbon dioxide | CO2 | 44.01 | 44.01 |
Sample Calculations, Gram formula mass worksheet answers
Berikut adalah beberapa contoh perhitungan GFM:
- Sodium chloride (NaCl)
- Massa atom Na = 22,99 g/mol
- Massa atom Cl = 35,45 g/mol
- GFM NaCl = (22,99 g/mol + 35,45 g/mol) = 58,44 g
- Water (H2O)
- Massa atom H = 1,01 g/mol
- Massa atom O = 16,00 g/mol
- GFM H 2O = (2 x 1,01 g/mol + 16,00 g/mol) = 18,02 g
- Carbon dioxide (CO2)
- Massa atom C = 12,01 g/mol
- Massa atom O = 16,00 g/mol
- GFM CO 2= (12,01 g/mol + 2 x 16,00 g/mol) = 44,01 g
Practice Problems
Berikut adalah beberapa masalah latihan untuk perhitungan GFM:
- Hitung GFM dari kalsium oksida (CaO).
- Hitung GFM dari asam sulfat (H2SO 4).
- Hitung GFM dari metana (CH 4).
Applications and Extensions
Perhitungan GFM memiliki berbagai aplikasi dalam kimia, termasuk:
- Menentukan jumlah zat dalam suatu sampel
- Mengkonversi antara massa dan jumlah mol
- Menentukan komposisi persentase senyawa
Selain itu, konsep GFM dapat diperluas ke konsep lain, seperti:
- Penentuan rumus empiris
- Stoikiometri reaksi kimia
- Kesetimbangan kimia
