Question

5.6 dm3 of a gas weighs 6.67 x 10-3 kg at STP. Hence the molecular weight of the gas is:

Answer 1

Answer:

Volume of the gas at STP = 5.6 dm

3

= 5.6 l.

Mass of the gas = 12g.

Volume at STP =

Molecularweight

Mass

×22.4

∴ Mol. wt. =

5.6

12

×22.4 = 48g.

Answer 2

The above answer is correct for the question so you can see it
