How much is the atomic mass of copper greater than the atomic mass of magnesium?

Copper – Cu;
Magnesium – Mg.
Atomic mass is the mass of one atom, it can be viewed in the periodic system of D. I. Mendeleev.
Ar (Cu) = 64;
Ar (Mg) = 24;
We calculate how much the atomic mass of copper is greater than the atomic mass of magnesium:
64/24 = 2.67.
Answer: 2.64 times the atomic mass of copper is greater than the atomic mass of magnesium
