Determine the number of atoms in 2.50 mol zn

For 1 mole of any substance, there are 6.02214086 × 10^23 particles (atoms, molecules, ions, etc. depending on the substance). This number is called Avogadro's Constant

So, for 1 mole of water, there are 6.02214086 × 10^23 water particles, and so on.

So in 2.5 moles of Zinc, you multiply Avogadro's Constant by 2.5 (the number of moles). In doing this you get the answer: 1.0554 × 10^24

The number of atoms in 2.50 mol of Zinc (Zn) is 1.5055 × 10²⁴ atoms

The Avogadro's number [tex]\mathbf{N_A}[/tex] refers to the number of fundamental particles such as atoms, molecules, compounds, per mole of a given substance. It is equal to 6.022×10²³ mol⁻¹

The number of atoms of ZInc (Zn) in 2.5 moles can be determined by using the formula:

number of atoms of Zn = moles of Zn × [tex]\mathbf{N_A}[/tex]

number of atoms of Zn = 2.5 moles × 6.022×10²³ mol⁻¹

number of atoms of Zn = 1.5055 × 10²⁴ atoms
