Answer:
1.505x10^24 atoms
Explanation:
From Avogadro's hypothesis, we understood that 1 mole of any substance contains 6.02x10^23 atoms.
From the above hypothesis, it became clear that 1 mole of Zn also contains 6.02x10^23 atoms.
Now, if 1 mole of Zn contains 6.02x10^23 atoms,
then 2.5 moles of Zn will contain = 2.5 x 6.02x10^23 = 1.505x10^24 atoms
Therefore, 2.5 moles of Zn contains 1.505x10^24 atoms
The number of Zn atoms in 2.50 moles of Zn is equal to [tex]1.505 \times 10^{24} [/tex] atoms.
To calculate the number of atoms present in a given amount of moles, it is necessary to use Avogadro's constant:
1 mole = [tex]6\times 10^{23} [/tex] atoms
So, in 1 mole of a substance we have [tex]6\times 10^{23} [/tex] atoms, having said that we can do the following calculation:
[tex]2.50 \times 6\times 10^{23^}[/tex]
[tex]= 1.5 \times 10^{24}[/tex] atoms of Zn
In this way, the number of Zn atoms in 2.50 moles of Zn is equal to [tex]1.505 \times 10^{24} [/tex] atoms.
