1 mole of gas occupies 22.4L
thus no of moles occupying 5.6L is = 5.6/22.4 =0.25
Now 1 mole of a substance weighs the same as it's atomic/molar mass
i.e. 1 mole = molar mass
0.25 = 7.5 g
Thus molar mass = 7.5/0.25 = 30
Thus the gas is NO (molar mass =30)
thus no of moles occupying 5.6L is = 5.6/22.4 =0.25
