Answer:

A mole of gold atoms has greater mass.

Explanation:

We know that #1# mole of any substance has #6.023 xx 10^23# number of atoms or molecules, this number is called Avogadro's number.

Therefore, number of atoms in #1# mole of silver is equal to the number of atoms in #1# mole of gold.

It follows that whichever element out of silver and gold has higher average atomic mass will have greater molar mass.

  1. Average atomic mass of silver#=107.8676# amu
  2. Average atomic mass of gold#=196.96655# amu

From above it is clear that a mole of gold atoms has greater mass.
