							The gas is Nitrogen.
using Gas Law,
PV=nRT

here, P=0.3 Bar,given weight=42g,volume=125L
T=300K
Volume in cubic meter=0.125 and pressure in pascal=30000
Pv=3750
RT=2494.32
by n=PV/RT
n=1.50, n is the number of moles and n=given weight/molar mass
molar mass=nxgivenweight
SO molar mass will be 28 which is of nitrogen.
