By referencing the periodic table, we can determine the molar mass of the atoms involved in the molecule CCl₄.
Carbon Tetrachloride (CCl₄) is composed of one Carbon (C) atom and four Chlorine (Cl) atoms.
To calculate the molar mass of CCl₄:
1. **Carbon (C):**
- Atomic Mass: 12.01 g/mol
2. **Chlorine (Cl):**
- Atomic Mass: 35.45 g/mol
Since there are four Chlorine atoms:
- Total mass of Chlorine atoms in one molecule of CCl₄ = 4 * 35.45 g/mol
- Therefore, CCl₄ = 12.01 g/mol + 4*(35.45 g/mol)
- CCl₄ = 12.01 g/mol + 141.8 g/mol
- CCl₄ = 153.81 g/mol
3. **Converting grams per mole to kilograms per mole:**
- 153.81 g/mol = 0.15381 kg/mol
Therefore, the molar mass of carbon tetrachloride (CCl₄) is **0.1538 kg/mol**, which corresponds to option F.
