Answer:  1 mol of Zn is 65.38g

Explanation: To find the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn. Hence, 1.34 g of Zn contains 0.020 moles of Zinc.

0.34 mole of atoms in 22.5 g Zn.

What are moles?

A mole is defined as 6.02214076 × [tex]10^{23}[/tex] of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.

To find the number of moles of Zn, we divide the given amount of Zn by the molar mass of Zn.

[tex]Moles = \frac{mass}{molar \;mass}[/tex]

[tex]Moles = \frac{22.5}{65.38 u}[/tex]

Moles = 0.34 mole

Hence, 0.34 mole of atoms in 22.5 g Zn.
