1.Molar mass is the mass of one mole per single element while atomic mass is the mass of an atom at rest or is the number of protons and neutrons.
2.Molar mass is measured in grams per mole while atomic mass is “unitless.”
3.Atomic mass is measured via mass spectrometry while molar mass is computed via atomic weight.
The correct answer among the choices given is option C. A bond that is not symmetrical along the axis between two atomic nuclei is a pi bond. These bonds are covalent bonds where one atomic orbital overlap to the other atomic orbitals.
