What is the % by mass of chlorine in CH2Cl2?

I calculated the molar mass of CH2Cl2 which is 84.93. I than calculated the molar mass of Cl2 which was 70.9. Than I divided 70.9 by 84.03 and my percent by mass of chlorine is 83.5 percent. Is this correct?

Yes. You made a typo with 84.03 when you intended to write 84.93
