Given dа ta:
Number of moles of NaOH = 2 mol
Number 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
So in 2 mol of NaOH:
1 mol = 6.022 * 10²³ molecules of NaOH
2 mol * 6.022 * 10²³ molecules NaOH / 1mol
12.044 * 10²³ molecules NaOH
we can determine the number of atoms of each elements.
one mole of NaOH contain 1 mole sodium atom one mole hydrogen atom and one mole of oxygen atom.
1 mol = 6.022 * 10²³ H atoms
1 mol = 6.022 * 10²³ O atoms
1 mol = 6.022 * 10²³ Na atoms
So 2 mol,
2 mol = 2 * 6.022 * 10²³ H atoms = 12.044 * 10²³ H atoms
2 mol = 2 * 6.022 * 10²³ O atoms = 12.044 * 10²³ O atoms
2 mol = 2 * 6.022 * 10²³ Na atoms = 12.044 * 10²³ Na atoms
Total = 36.132 * 10²³ atoms
