* Empirical Formula: The empirical formula tells you the simplest whole-number ratio of atoms in a compound. CCl tells us there's one carbon atom for every chlorine atom.
* Molecular Formula: The molecular formula shows the actual number of atoms of each element in a molecule.
To find the molecular formula, you need the following:
1. Molar Mass of the Empirical Formula: Calculate the molar mass of CCl:
* Carbon (C): 12.01 g/mol
* Chlorine (Cl): 35.45 g/mol
* Molar Mass of CCl: 12.01 + 35.45 = 47.46 g/mol
2. Divide the Given Molar Mass by the Empirical Formula Molar Mass:
* 284.77 g/mol / 47.46 g/mol = 6
3. Multiply the Subscripts in the Empirical Formula by the Result:
* CCl * 6 = C₆Cl₆
Therefore, the molecular formula of the compound with a molar mass of 284.77 g/mol and the empirical formula CCl is C₆Cl₆.
Important Note: The molecular formula could be different if the given molar mass is not accurate or if there's an error in the empirical formula provided.
