Answer 1

Answer:

Here's the master formula to do all sum of mole concept.

This formula is:

n=W/M=N/Nā=V(litre)/22.4

Here, W= Mass

M=Atomic mass of molecular mass

N=Number of particles can be number of atoms, number of ions, number of molecules, number of electrons, number of protons or number of neutrons.

Nā= Avogadro number

V(litres)= Volume of gas in litres

and 22.4 is constant value.

Here, this part N/Nā is applicable for only gases.
