Question

How many moles of silver is 8.46x10^24 atoms of silver

Answer 1

This question is providing the number of atoms of silver a sample has as 8.46x10²⁴ so the moles are asked and turn out equal to 14.0 moles according to the following work:

First of all, we recall the concept of Avogadro's number which states that one mole of any substance is equal to 6.022x10²³ representative particles, say atoms, molecules or ions. Next, we write the conversion factor to guarantee the acquiring of moles by cancelling out the atoms:

$8.46x10^{24}atoms*\frac{1mol}{6.022x10^{23}atoms}$

And finally, we divide the initial atoms by the Avogadro's number to obtain:

$14.0mol\ Ag$

Which has to be rounded to three significant figures because the initial number of atoms have three significant figures as well.
