We need to know the diameter of the wire to calculate the volume and the mass.
Number of atoms is: 2,58.1023.r2, where r is the radius of the wire.

What is an atom with 29 protons and 31 neutrons?
Copper-31. All atoms with 29 protons are Copper.
Why electrons path is helical?
In a copper wire each copper atom has two loosely coupled outer thermal atoms (this is why copper has a plus 2 valence)When an electrical current is passed through the copper wire, the two thermal atoms are pushed onto the next copper atom. Temperature of a copper atom depends on how fast the electrons orbit in the respective copper atoms.Since thermal electrons make up the electric current which flows through the copper wire, the electrons will continue to orbit the copper atoms as they move across, thus travelling along a helical path
How do you calculate diameter of a copper wire conductor and how do we calculate resistance of a copper wire conductor of a particaular length?
You go to the NEC and look at the chart for developed length and the ambient temperature and the load factor and if it solid or stranded wire as stranded allows for more voltage
