1. Find the molar mass of CCl4:
* Carbon (C) has a molar mass of 12.01 g/mol.
* Chlorine (Cl) has a molar mass of 35.45 g/mol.
* CCl4 has 1 carbon atom and 4 chlorine atoms.
* Molar mass of CCl4 = (12.01 g/mol) + (4 * 35.45 g/mol) = 153.81 g/mol
2. Calculate the number of moles:
* Moles = Mass / Molar mass
* Moles = 56 g / 153.81 g/mol
* Moles ≈ 0.364 mol
Therefore, approximately 0.364 moles of CCl4 are present in 56g.
