Q12 of 100 Page 33

The quantity represents

We know that ideal gas equation is


PV=nRT


Where V= volume of gas


R=gas constant


T=temperature


n=number of moles of gas


P=pressure of gas.


Gas constant R=kNA


Where k=Boltzmann constant


NA=Avogadro number


So, we can ideal gas equation as


PV=nkNAT



Now, we know that


n=number of molecules of gas ……(ii)


Therefore, from equation (i) and (ii)


Number of molecules of gas=
