Atomic Mass Units and e/u The atomic mass of an isotope is its mass in atomic mass units, where 1 u = 1.661 x 10-27 kg. The ratio of the fundamental charge, e, to the atomic mass unit, u, is e/u = 9.65 x 107 C/kg. 1. Using Atomic Mass Units (a) What is the mass of an isotope with an atomic mass of 19.2 u? m = 31.89e-27 kg (b) What is the charge-to-mass ratio of a +2Li-6 ion, which has an atomic mass of 6.015? 오 = 2.4e6 X C/kg m
