Answer:
The molar mass of copper (II) nitrate is 187.5 g/mol.
Explanation:
The molar mass is the mass of all the atoms in a molecule in grams per mole. To calculate the molar mass of a molecule, we first obtain the atomic weights from the individual elements in a periodic table. We then count the number of atoms and multiply it by the individual atomic masses.
False... The number of electrons in the outer shell of the atom of the element determines it's reactivity. <span />
I think because each element has its own number of protons and neutrons, giving it its own atomic number and mass (correct me if I’m wrong please)
