It's Copper Nitrate.

So you take the atomic mass of each element and multiply their corresponding subscript then add them all up.

Element                       Atomic Mass                         Subscript             Equation
Cu                                63.546                                    1                     63.546x1
N                                  14.00674                                2                     14.00674x2
O                                  15.994                                    6                     15.994x6

63.546+28.01348+95.964=187.5

And the unit is g/mol so the molar mass of Cu(NO3)2 is 187.5g/mol.

You should really name it copper (II) nitrate.  Granted, the Cu+ cation isn't that common, but good IUPAC nomenclature insists you put the Stock notation in anyway.
