50.0 g of Cl 2 contains ________ mol Cl 2 .

To find the number of moles in 50.0 g of Cl 2 , we need to use its molar mass. Molar mass of Cl 2 = 97.548 g/mol Number of moles = mass/molar mass Number of moles = 50.0 g/ 97.548 g/mol Number of moles = 0.512 mol Therefore, 50.0 g of Cl 2 contains 0.512 mol Cl 2 . Option C is the correct answer.
