Petra · Answer

Answer: 	The equivalence factor is 1 mole / 6.023 x 10²³ molecules. 	 		Explanation: 		Avogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023 x 10²³ particles per mole. The Avogadro number applies to any substance. 		A rule of three can be applied as follows: if 6.023 x 10²³ molecules are contained in 1 mole, how many moles will be contained in 4.28 x 10¹⁹ molecules? 		moles = 4.28 x 10¹⁹ molecules * (1 mole / 6.023 x 10²³ molecules) 		moles ≈ 7.106 x 10⁻⁵ 		So, the equivalence factor is 1 mole / 6.023 x 10²³ molecules.
