Answer:

Well, the molar mass of #HgI_2=545.40*g*mol^-1#.

Explanation:

How did I get this molar mass? I added the molar masses of elemental mercury, and twice the mass of atomic iodine:

#(2xx126.9+200.6*g*mol^-1)*g*mol^-1# #=# #454.40*g*mol^-1#.

But from where do I get the atomic mass of cadmium to make an equivalent calculation?
