18.066 * 10²³ particles
Explanation:
Given dа ta:
Number of moles = 3 moles
Number of particles = ?
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 3 moles of substance:
One mole = 6.022 * 10²³ particles
3 mol * 6.022 * 10²³ particles / 1 mol = 18.066 * 10²³ particles
