Question

Suppose a piece of silver jewelry contains 5.23×1022 atoms of silver (ag). part a how many dozens of silver atoms are in the piece of jewelry? express your answer numerically in dozens.

Answer 1

Answer:
number of dozens = 4.35834 * 10^21 dozens

Explanation:
A dozen contains 12 atoms. To know the number of dozens containing
5.23 * 10^22 atoms, all we have to do is cross multiplication as follows:
1 dozen ...........> 12 atoms
?? dozens ......> 5.23 * 10^22 
number of dozens = (5.23 * 10^22 *1) / (12)
number of dozens = 4.35834 * 10^21 dozens

Hope this helps :)

Answer 2

The silver jewelry containing $\rm 5.23\;\times\;10^2^2$ atoms of Ag parts  4.35 $\rm \times\;10^2^1$ dozens of silver atoms.

Dozen is the unit of measurement. The number of atoms in 1 dozen  = 12 atoms.

For the reaction, for $\rm 5.23\;\times\;10^2^2$ atoms of Ag are :

12 Atoms = 1 dozen

$\rm 5.23\;\times\;10^2^2$ atoms  = $\rm \dfrac{5.23\;\times\;10^2^2}{12}\;\times\;1$ dozen

$\rm 5.23\;\times\;10^2^2$ atoms  = 4.35 $\rm \times\;10^2^1$ dozen.

The silver jewelry containing $\rm 5.23\;\times\;10^2^2$ atoms of Ag parts  4.35 $\rm \times\;10^2^1$ dozens of silver atoms.
