Find the sum of molar mass of D , E , R , P D, E, R, P and Y Y .

Molar Masses: H = 1 , C = 12 , O = 16 , F = 19 , C l = 35.5 \ce H=1, \ce C=12, \ce O=16, \ce F=19, \ce {Cl}=35.5 .

Note: It is not SO3Cl2, it is SO2Cl2.

There will be H2SO4 from I to J.

There will be Se from J to K.

C2H4 is added in J.


The answer is 324.5.
