Hey there!
They have the same amount of particles, but the mole of gold has a higher mass.
An element's molar mass is the mass of one mole of that element.
One mole of atoms is 6.022 x 10²³ atoms.
The molar mass of silver is 107.87 grams, and the molar mass of gold is 196.97 grams.
So, a mole of gold has a higher mass.
Hope this helps!
