To find the mass of 0.500 mol of CF₂Cl₂, we need to use its molar mass. The molar mass of CF₂Cl₂ is 120.91 g/mol (you can find this by adding the atomic masses of each element in the compound). Now, we can use the following equation to find the mass: mass = number of moles x molar mass mass = 0.500 mol x 120.91 g/mol = 60.455 g Rounded to three significant figures, the answer is 60.5 g, which is choice B.
