A silver ring contains 0.0134 mmol Ag. How many silver atoms does it contain?
see below.
To determine the number of silver atoms in the ring, we need to use Avogadro's number, which relates the number of particles in a mole of a substance.
Avogadro's number is defined as 6.022 x 10^23 particles per mole. It provides the number of atoms, molecules, or particles in one mole of a substance.
Given the moles of silver in the ring as 0.0134 mmol, we can use Avogadro's number to calculate the number of silver atoms:
Number of silver atoms = moles of silver x Avogadro's number
Substituting the given value:
Number of silver atoms = 0.0134 mmol x 6.022 x 10^23 atoms/mol
Now, let's evaluate the expression:
Number of silver atoms = 0.0134 x 6.022 x 10^23 atoms
= 8.057 x 10^21 atoms
Therefore, the silver ring contains approximately 8.057 x 10^21 silver atoms.
