Answer: a) the unit used to count a large number of very small objects.
b) [tex]6.02214\times 10^{23}[/tex] particles
Explanation:
According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP, contains avogadro's number of particles and weighs equal to the molecular mass of that substance.
A mole is defined as the amount of substance that contains Avogardro number of the substance. Avogadro's number is given by [tex]6.023\times 10^{23}[/tex] particles. It is used to represent large number of particles.
Thus the correct statements are : A mole is the unit used to count a large number of very small objects. It is equal to [tex]6.02214\times 10^{23}[/tex] particles.
A mole is the representation of the counting of small molecules, that has been equivalent to [tex]\rm 6.023\;\times\;10^2^3[/tex] particles. Thus, option B and C are correct.
The substance or compound has been consisted of the molar mass, that has been equivalent to the mass of each atom in a molecule. The molar mass of a compound has been given as the mole.
Moles
The moles have been defined as the molar mass of a compound or element.
- The mole has not been used for the determination of the energy of the substance. Thus, option A is incorrect.
- The mole has been given as the counting number for the small objects. It has been given as the number of molecules in a mole of sample has been equivalent to the Avogadro number. Thus, option B is correct.
- The Avogadro number has been [tex]\rm 6.023\;\times\;10^2^3[/tex] . Thus, the moles has been the representation of the [tex]\rm 6.023\;\times\;10^2^3[/tex] particles. Hence, option C is correct.
