Answer:
9.03 x 10²³ atoms in the pennies
Explanation:
I suspect you want to find the number of atoms that makes up the given moles of the pennies:
Number of moles of pennies = 1.5 moles
Solution:
The mole can be defined as the amount of a substance that contains Avogadro's number of particles i.e 6.02 x 10²³atoms.
number of atoms = number of moles x 6.02 x 10²³ = 1.5 x 6.02 x 10²³
number of atoms = 9.03 x 10²³ atoms
