How many atoms are present in a piece of sterlingsilver jewelry weighing 33.14 ? (Sterling silver is a silver-copper alloy containing 92.5% by mass.)
There'd be no way to tell for sure, but it would probably be about 17,500,000,000,000,000,000 (1.75 X 10^19) atoms.
Yes, it is possible.
48,177 134 32.1023 atoms
The chemical formula of propane is C3H8; 11 atoms are present in the molecule.
A macromolecule
This depends on the percentage of copper in the alloy.If this alloy contain 7,5 % Cu the number of copper atoms is approx. 0,2355.10.e+23.

A piece of jewelry can range from a small earring to a large necklace. In that case, there can also be varying number of moles of silver atoms in a piece of jewelry. Plus, not all jewelry contain silver in them. Thus, there is no specific answer to this question
0.5 moles.
4 oxygen atoms are present
There are carbon and hydrogen atoms present in hydrocarbons.
