How many moles of silver atoms are in the piece of jewelry? ?

Answer : A piece of jewelry can range from a small earring to a large necklace. So, in this case, there is varying number of moles of silver atoms may be present in a piece of jewelry.

Also, it can happen that all jewelry doesn't contains silver in them. Thus, there is no specific answer to this question.

But if the weight of silver is known then we can calculate the atoms in it by comparing 1 mole with avogadro number of atoms.

answer is: naturally occurring solid, inorganic compound or element is mineral.

minerals usually have crystalline form, that means than crystal constituents (atoms, molecules or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions.

for example magnetite is a mineral of iron oxide (fe₂o₃).

calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (caco₃).

dolomite is an   carbonate mineral composed of calcium magnesium carbonate (camg(co₃)₂).
