Answer:
3.91x10²³ atoms of lead
Explanation:
In chemistry, a mole of a substance is defined as 6.022x10²³ particles that could be atoms, molecules, ions, etc.
As you can see, in the problem, you have 0.650moles of lead in a fishing line sinker, the present atoms are:
[tex]0.650mol Pb \frac{6.022x10^{23}atoms}{1mol}[/tex] = 3.91x10²³ atoms of lead
