A silver sample contains 52 atoms each having 60 neutrons and 48 atoms each having 62 neutrons What is the sample's average atomic mass?
First, calculate the mass contribution of each type of atom:
For atoms with 60 neutrons: mass = (60 neutrons + 48 protons) = 108 amu
For atoms with 62 neutrons: mass = (62 neutrons + 48 protons) = 110 amu
Calculate the weighted average based on the number of each type of atom to find the sample's average atomic mass.
