12.044 * 10²³ atoms
Explanation:
Given dа ta:
Number of moles of Zn = 2 mol
Number of atoms = ?
Solution;
The given problem will solve by using Avogadro number.
It is the number of atoms, ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 * 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 * 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 * 10²³ atoms of hydrogen
For Zn:
1 mol of Zn = 6.022 * 10²³ atoms
2 mol * 6.022 * 10²³ atoms / 1mol
12.044 * 10²³ atoms
