The molar mass of Cu(C104)2 is the mass of one mole of the compound. To find the molar mass, we need to know the atomic weights of the elements in the compound and the number of atoms of each element.
Cu(C104)2 is a complex ion made up of copper (Cu) and a large organic molecule known as a porphyrin. The porphyrin molecule contains four nitrogen atoms, four carbon atoms, and eight hydrogen atoms.
The atomic weight of copper is 63.55 g/mol, the atomic weight of carbon is 12.01 g/mol, and the atomic weight of hydrogen is 1.01 g/mol.
To find the molar mass of Cu(C104)2, we need to add up the atomic weights of all the atoms in the compound:
Molar mass = (1 mol Cu * 63.55 g/mol Cu) + (4 mol C * 12.01 g/mol C) + (8 mol H * 1.01 g/mol H) + (4 mol N * 14.01 g/mol N)
This simplifies to:
Molar mass = 63.55 g/mol + 48.04 g/mol + 8.08 g/mol + 56.04 g/mol
The molar mass of Cu(C104)2 is therefore 175.71 g/mol.
