To find the mass of 9.86 × 10^24 molecules of COS, we first need to calculate the number of moles of COS:

9.86 × 10^24 molecules ÷ 6.022 × 10^23 molecules/mol = 16.36 mol COS

Now we can use the molar mass of COS to find the mass:

16.36 mol × 44.01 g/mol = 720 g

Therefore, the answer is C) 720 g.
