A silver ornament of mass ‘m’ gram is polished with gold equivalent to 1% of the mass of silver. Compute the ratio of the number of atoms of gold and silver in the ornament.
Mass of silver = m g.
Mass of gold = m / 100 g.
Number of atoms of silver = Mass / Atomic mass x N_A,
= m / x N_A.
Number of atoms of gold = m / 100 x x N_A.
Ratio of number of atoms of gold to silver = Au : Ag.
= m / x 197 x N_A : m / 108 x N_A.
= 108 : 100 × 197.
= .
