Question

One gram mole of a gas at ntp occupies 22.4 litre. This fact was derived from

Answer 1

according to avogadro law :- under similar conditions of temperature and pressure equal volume of gases contains equal no of molecules

i.e. pv=nRT

v=nRT/p

we put n=1 R, T and P value at NTP

then we find v=22.4L
