Answer:
To calculate the mass of an atom of silver, we need to know the number of protons and neutrons in the nucleus of the atom. The atomic number of silver is 47, which means it has 47 protons in its nucleus. The mass number of silver is 108, which means that the total number of protons and neutrons in its nucleus is 108. Therefore, the mass of an atom of silver is approximately 108 times the mass of a single proton or neutron. This is because the mass of an electron is much smaller than the mass of a proton or neutron and can be neglected. The mass of a single proton or neutron is approximately 1 atomic mass unit (amu), so the mass of an atom of silver is approximately 108 amu.
