Question

Avagadro’s number:

A: Is constant irrespective of mass of the gases

B: Varies according to the mass of the gases

C: Varies according to the pressure on the gases

D: All of the Above

Answer 1

A: Is constant irrespective of mass of the gases

Step-by-step explanation:

Avagadro's number, denoted by nA, is a number that represents the units in one mole of any substance. The number is 6.02214076 × 10²³ and the units can be atoms, molecules, ions, formula units etc.

That is;

1 mole of a substance = 6.022 × 10²³atoms, molecules, ions, electrons etc.

It is important to note that the Avagyadro's number is constant irrespective of mass of the gases that are involved.
