Answer:
3.011 × 10²³ particles
Step-by-step explanation:
Given data:
Number of moles = 0.5 mol
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.
one mole of substance = 6.022 × 10²³ particles
For 0.5 mole of substance:
0.5 mol × 6.022 × 10²³ particles / 1 mol
3.011 × 10²³ particles
