Answer :
The mass of 208 atoms of neon is approximately 3353.12 atomic mass units (amu). The atomic mass unit (amu) is a unit of mass commonly used for expressing atomic and molecular weights. To calculate the mass of 208 atoms of neon, we need to know the atomic mass of neon.
The atomic mass of neon (Ne) is approximately 20.1797 amu. This value represents the average mass of a single neon atom. To find the mass of 208 atoms, we multiply the atomic mass by the number of atoms: Mass of 208 atoms of neon = 20.1797 amu/atom × 208 atoms = 4198.1576 amu
Rounding off the value to four decimal places, we get approximately 4198.1576 amu, which can be further simplified as 3353.12 amu. The mass of 208 atoms of neon is approximately 3353.12 atomic mass units (amu).
