Answer:
It is given that 1 litres gas weighs 2.5 g
So 22.4 litre weighs = 56 grams
The molecular weight of the gas is 56 g/mol.
Hope it helps.

Answer:
The molecular weight is 56 g.
Explanation:
Given that 1 of gas weights 2.5 g at STP. We have to find the molecular weight of the gas.
Given volume = 1
We know that 1 = 1 L
Therefore 1 L weights 2.5 g
1 mole of any gas occupies 22.4 L at STP.
So 22.4 L weights 22.4 × 2.5 = 56 g
Therefore, the molecular weight is 56 g.
