Question

calculate mass of an atom of silver

Answer 1

The atomic mass of silver is 108 u and molar mass of silver is 108 g/mol. This means there are 6.023 X 10²³ atoms of silver in 108 g of silver. Thus

mass of 6.023 X 10²³ atoms of silver = 108 g

mass of 1 atom of silver = 108 / (6.023 X 10²³) g

= 1.7931 X 10^-22 g

Thus the mass of an atom of silver is 1.7931 X 10^-22 g.
