The amount of moles is also defined as n = N/NA, where
n - amount of moles
N - amount of atoms
NA - Avogadro constant (approx. 6.02214179×1023 mol-1), therefore
N = n×NA = 0.263×6.02214179×1023 = 1,583823291×1023 atoms.
Sterling silver is typically about 92.5% silver. To calculate the number of silver atoms in the jewelry piece, you'd first determine the mass of the silver in the jewelry (0.925 * 33.14 g) and then convert this mass to moles of silver (using the molar mass of silver). Finally, you'd use Avogadro's number to convert moles to atoms.
The answer is 6,31 moles Ag.
One formula unit of silver sulfate, Ag2SO4 has 7 atoms.
There are 10 hydrogen atoms present in 4C2H5OH.

A mole of silver contains approximately 6.022 x 10^23 atoms.
The answer is 6,31 moles Ag.
There are 6.022x1023 atoms in a mole. You multiply 6.022x1023 by 8.68, which equals 52.20796x1023 atoms
One formula unit of silver sulfate, Ag2SO4 has 7 atoms.
There are 10 hydrogen atoms present in 4C2H5OH.
To determine the number of Cu atoms in the piece of sterling silver jewelry, you would first need to convert the weight of the jewelry to moles using the molar mass of silver. Then, since sterling silver is typically 92.5% silver and 7.5% copper by weight, you can calculate the number of moles of copper present. Finally, use Avogadro's number to convert from moles to atoms.
There are 5 atoms in silver nitrate (1 silver, 1 nitrogen and 3 oxygens).
