Answer / masood rahman

1 nm3 X MW/22.4=1 Kg
for Oxygen MW=32, 22.4 (molar volume)
so,1 Nm3= 22.4/32 i.e. 0.7 KG

Answer / anand

Since density=mass/volume
Here,V=1m^3
Therefore,
mass=density
For example, at O C density of oxygen=1.43 kg/m^3
mass=1.43 kg

Answer / peter shonfield

Answer depends on temperature and can be calculated based on the ideal gas law. PV=nRT
P=pressure (atmospheres)
V=volume (litres)
n=moles of gas
T=temperature (K)
R=gas constant = 0.08206

Therefore at 25 deg C (298K) the volume occupied by 1 mole of oxygen= nRT/P = 1*0.08206*298/1 = 24.45 litres

Oxygen has a molecular mass of 32 g

Therefore mass of 1 m3 oxygen = 32/24.45*1000 = 1309 g = 1.309 kg

Answer / pravin jadhav

kg of gas = Nm3* Mol weight/ 22.4138

thus
1 kg of oxygen = 32.22/22.4138 Nm3
0.695 nm3 of oxygen

Answer / harshal shah

1 cubic meter= 1000 kg of oxygen.
