Apure silver ring contains 2.60 *10^22 silver atoms. how many moles of silver atoms does it contain?

The silver ring contains 0.043 mole of silver.

From Avogadro's hypothesis, we understood that:

With the above information in mind, we can calculate the number of mole of 2.60×10²² atoms of silver. This can be obtained as follow:

6.02×10²³ atoms = 1 mole of Silver

Therefore,

2.60×10²² atoms = 2.60×10²² / 6.02×10²³

Therefore, the silver ring contains 0.043 mole of silver.
