- The atomic mass of 20Ne is 19.9924 amu, 21Ne is 20.9938 amu and the atomic mass of22Ne is 21.9614 amu. In a natural sample, 90.48 % of the atoms are 20Ne, 0.27 % of the atoms are 21Ne, and 9.25 % are 22Ne. Calculate a value for the molar mass of neon in g mol-1, given one atomic mass unit (amu or u) equals 1.66054 x 10─24 g. Show all working.
