Question

the number of atoms, molecules or ions present in one mole in: (a)6.02×10²³ (b)6.02×10²⁷ (c)6.02×10-²³ (d)60.2×10²²​

Answer 1

Answer:

The number of atoms, molecules or ions present in one mole is $6.022 *10^{23}$ (option a).

Explanation:

A mole is a unit of measurement for the amount of material present in a sample. The Avogadro's constant is a number equal to $6.022 *10^{23}$ particles, usually known as a mole. These particles can be any type of species, that is, atoms, molecules, electrons, protons, neutrons, etc. This value,$6.022 *10^{23}$  (Avogadro's constant), is based on the number of atoms in 12 g of the $C^{12}$ carbon isotope.

Answer 2

Answer:

The number of atoms, molecules or ions present in one mole is $6.02$ × $10^{23}$

Explanation:

The number of atoms, molecules, or ions in one mole of a substance is known as the Avogadro number.

That is one mole is represented by the Avogadro number of molecules or atoms or ions.

A mole of a substance is defined as $6.023$×$10^{23}$ units of that substance (such as atoms, molecules, or ions). Avogadro's number, often known as Avogadro's constant, is $6.023$× $10^{23}$
