Answer:
6.022 x 10²³; it is a conversion factor between moles and number of particles
Explanation:
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 of hydrogen = 6.022 × 10²³ atoms of hydrogen
238 g of uranium = 1 mole of uranium = 6.022 × 10²³ atoms of uranium
By taking ions:
62 g of NO⁻₃ = 1 mole of NO⁻₃ = 6.022 × 10²³ ions of NO⁻₃
96 g of SO₄²⁻ = 1 mole of SO₄²⁻ = 6.022 × 10²³ ions of SO₄²⁻
The Avogadro number has been [tex]\rm 6.023\;\times\;10^2^3[/tex]. It acts as a conversion factor between moles and the number of particles. Thus option D is correct.
Avogadro's number has been the constant value that gives the value of the number of atoms of a molecule in 1 mole of the sample.
The Avogadro number has been the proportionality constant and has been named after Sir Amedeo Avogadro. The numerical value that describes the value of the Avogadro number has been known as the Avogadro number or Avogadro constant. The value of the Avogadro constant has been [tex]\rm 6.023\;\times\;10^2^3[/tex].
In the mole concept, the value of the Avogadro number gives information about the number of atoms in a mole of the sample. Thus it acts as a conversion factor between moles and the number of particles.
Thus, the Avogadro number has been [tex]\rm 6.023\;\times\;10^2^3[/tex]. It acts as a conversion factor between moles and the number of particles. Thus option D is correct.
