Web25 de ago. de 2024 · Upon summing all four results, the mass of 1 mol of the mixture of isotopes is to be found. 2.86g + 49.64g + 45.74g + 108.98g = 207.22g. The mass of an average lead atom, and thus lead's atomic mass, is 207.2 g/mol. This should be confirmed by consulting the Periodic Table of the Elements. Exercise 1.9.1: Boron. Web18 de mai. de 2024 · Figure 2.2. 1: A Simple Periodic Table. There is an easy way to represent isotopes using the atomic symbols. We use the construction: X Z A. where X is the symbol of the element, A is the mass number, and Z is the atomic number. Thus, for the isotope of carbon that has 6 protons and 6 neutrons, the symbol is: C 6 12.
