Question

Relationship of mole to mass of the particles and numbers.

Answer 1

Answer:

Explanation:

No of moles [n]= mass/molar mass

1 mole = 6.022 x 10^23 atoms

= 6.022x10^23 molecules

Answer 2

The relationship of mole to mass of the particles and numbers is best represented by Avogadro's Number.

Explanation:

• Mole concept is used to convert between mass and number of particles.
• One mole of any substance is equal to $6.022$ × $10^{23}$ units of any substance.
• These substances are atoms, molecules, or ions.
• The number  $6.022$ × $10^{23}$  is known as Avogadro's number or Avogadro's constant.
• Mass is the fundamental property of a substance.
• The number of moles is the mass of a substance divided by molar mass.
• Molar mass is the atomic mass number of an element.
