Final answer:
The mass of 0.500 mol of dichlorodifluoromethane, CCl2F2, is calculated by multiplying the number of moles by its molar mass, resulting in a mass of 60.47 grams.
Step-by-step explanation:
The question aims to determine the mass of 0.500 mol of dichlorodifluoromethane (CCl2F2). To find this value, we will calculate it using the compound's molar mass and the number of moles given. The molar mass of dichlorodifluoromethane can be found by adding together the atomic masses of two carbon atoms, two chlorine atoms, and two fluorine atoms from the periodic table. The atomic masses are approximately Carbon (C) = 12.01 g/mol, Chlorine (Cl) = 35.45 g/mol, and Fluorine (F) = 19.00 g/mol.
Thus, the molar mass of CCl2F2 = (2 × 12.01 g/mol) + (2 × 35.45 g/mol) + (2 × 19.00 g/mol) = 120.94 g/mol. Now, using the molar mass:
Total mass = moles × molar mass = 0.500 mol × 120.94 g/mol = 60.47 g
Therefore, the mass of 0.500 mol of dichlorodifluoromethane is 60.47 grams.
