Consider the quantity of an ideal gas where M is the mass of the gas. It depends on the

In quantity ,

M=mass of the gas

k= Boltzmann constant

t= temperature

p=pressure

V=volume

We know ideal gas equation

pV=nRt

Where V= volume of gas

R=gas constant =8.3JK^-1mol^-1

t=temperature

n=number of moles of gas

p=pressure of gas.

Gas constant R=kN_A

Where k=Boltzmann constant

N_A=Avogadro number

So, we can ideal gas equation as

pV=nkN_At

Now, we know that

n=number of molecules of gas ……(ii)

Therefore, from equation (i) and (ii)

Number of molecules of gas= …. (iii)

Using equation (iii) quantity becomes

Hence, quantity depends on the nature of gas.
