WebWe are going to add 0.0111 times 13.0034. And I know it's going to do this multiplication first because it's a calculator knows about order of operations. And so, that's all going to be, as you can see, 12.01113774, which, if you were to round to the hundredths place, is how this atomic weight was gotten. 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. WebIsotope Pennies Lab. Introduction: Isotopes are atoms, of a given element, that have the same number of protons, but a different number of neutrons in the nucleus. For example: C-12 and C-14 are carbon isotopes. They each have 6 protons (atomic # = 6), but one has 6 neutrons while the other has 8 neutrons. imed pet request form
