In addition to helping these vital functions continue in the body, the list of glutathione benefits is long and wide: Plays a crucial role in immune function. (8) Promotes T-cell function, which is critical for a strong immune system.
Average atomic mass of copper = (62.93 amu Ã 0.6909) + (64.94 amu Ã 0.3091)= 63.55. From the calculation, we know that an AVERAGE atom of copper has a mass of 63.55 amu. Notice that in this problem, we would predict that the average is closer to the weight of the lighter isotope.
According to HowStuffWorks, an atomic mass unit is defined as the mass of a single proton or neutron. Hydrogen, the lightest element, has an average mass of 1.00794 amu. A carbon-12 atom is made up of six protons and six neutrons, hence 12 atomic mass units. The mass of the electron is considered negligible, therefore electrons are not counted in measuring an atom's atomic mass.
