Answer :
Final answer:
The number of moles of zinc in 1.57 x 10^24 Zn atoms is approximately 2.61 moles. This calculation is achieved by dividing the number of atoms by Avogadro's number.
Explanation:
To find the number of moles of a substance, you can use Avogadro's number, which is 6.022 x 10^23 atoms per one mole. You need to divide the number of atoms, which is 1.57 x 10^24, by Avogadro's number.
The calculation looks like this: (1.57 x 10^24) / (6.022 x 10^23) = 2.61 moles, approximately.
So, there are approximately 2.61 moles of zinc in 1.57 x 10^24 Zn atoms.

Using Avogadro's number (6.022 x 10²³ atoms in a mole), we find there are 2.61 moles of zinc in 1.57x10²⁴ zinc atoms.
To calculate the quantity in moles of a given number of atoms, we use Avogadro's number, which states there are 6.022 x 10²³ atoms in a mole. Therefore, to find the number of moles of zinc in 1.57x10²⁴ atoms, we would divide the total number of atoms by Avogadro's number. The calculation as follows:
1.57 x 10²⁴ atoms / 6.022 x 10²³ atoms/mol = 2.61 mol
The main answer is 2.61 moles of zinc.
In conclusion, that there are 2.61 moles of zinc in 1.57x10²⁴ zinc atoms when we apply Avogadro's number.
