Question

calculate the mass of(1)an atom of silver (2)a molecule of carbon dioxide

Answer 1

1).   Mass of 6.02×10^23 atoms of silver = 108 g  Therefore, mass of 1 atom of Silver =108 /6.02×10^23 = 17.94 ×10^-23 g  2).  Mass of 6.02×10^23 molecules of CO2 = 44g  Therefore, mass of 1 molecule of CO2 = 44/6.02×10^23 = 7.30 ×10^-23g
