Answer:
Avogadro's number
Explanation:
The name for conversion factor that takes you from moles of compound "A" to ions of component "A" is Avogadro's 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
98 g of SO₄²⁻ = 1 mole = 6.022 × 10²³ ions of SO₄²⁻
Consider the example:
5 g of sodium chloride contain how many sodium ions?
Number of moles = mass/ molar mass
Number of moles = 5 g/ 58.5 g/mol = 0.1 mol
NaCl = Na⁺Cl⁻
0.1 × 6.022 × 10²³ ions = 0.6022× 10²³ ions
