Well, given that number of chlorine atoms...there are HALF this number of methylene chloride molecules...

Explanation:

And a molar quantity of....

#(3.67xx10^24*"chlorine atoms")/(2*"chlorine atoms"*"molecule"^-1)=#

#1.835xx10^24*"molecules"#

#(1.835xx10^24*"molecules")/(6.022xx10^23*"molecules"*mol^-1)=3.05*mol#

..What is the mass of this molar quantity?
