The molar mass of a molecule corresponds to the sum of the atomic weights of each element multiplied by the number of atoms of the respective element. The atomic weights can be found in the periodic table. For each element the atomic weight is:
Cu=63.546u
S= 32.065 u
O4= 15.999u
The molar mass of the molecule will be:
[tex]MolarMassCuSO_4=1\times63.546u+1\times32.065u+4\times15.999u[/tex][tex]MolarMassCuSO_4=63.546u+32.065u+63.996u[/tex][tex]MolarMassCuSO_4=159.607g/mol[/tex]Answer: The molar mass of CuSO4 is 159.607g/mol
