On a planet in a separate solar system, silver has an atomic weight of 107.41 g/mol. a) Much like on Earth, silver has two isotopes on this planet. Using the atomic weights of these two isotopes shown below, determine the abundance of each of these isotopes on this distant planet. Isotope Atomic weight (g/mol) 106.91 107 Ag 109 Ag 108.90 % 107 Ag 109 Ag b) The coins on this planet are made entirely of silver! Determine the number of atoms of silver in a 2.25 g coin in this other world. atoms
