Final answer:
The mass of 0.500 moles of dichlorodifluoromethane (CF2Cl2) is calculated by finding the molar mass of CF2Cl2 and then multiplying by the number of moles, resulting in 60.46 g.
Step-by-step explanation:
To calculate the mass of 0.500 moles of dichlorodifluoromethane (CF2Cl2), you first need to determine the molar mass of the compound. This is done by adding together the atomic masses of all the atoms in the molecule:
- Carbon (C): 12.01 g/mol
- Fluorine (F): 19.00 g/mol × 2 = 38.00 g/mol
- Chlorine (Cl): 35.45 g/mol × 2 = 70.90 g/mol
The molar mass of CF2Cl2 = 12.01 g/mol + 38.00 g/mol + 70.90 g/mol = 120.91 g/mol.
To find the mass of 0.500 moles of CF2Cl2, multiply the number of moles by the molar mass:
Mass = moles × molar mass = 0.500 moles × 120.91 g/mol = 60.46 g
Therefore, the mass of 0.500 mol of dichlorodifluoromethane is 60.46 g.
