Ans: Molecular weight is the atomic mass unit of each of the atoms present in the compound.
One mole of gas occupies a volume of 22.4 L at STP ( standard temperature and pressure) where temperature is 273 K and pressure of 1 atm.
Now, according to the question,
Weight of 300ml of the gas is 0.368g
So, weight of 22400 ml of gas will be = 0.368 x 22400/300
= 27.47 g/mol
So, as one mole of gas occupies 22.4L, therefore,the weight will be the molecular weight of the gas.
