Question

molecular mass= weight of 22.4 liter of gas​

Answer 1

Answer:

Any gas can be identified from its molecular weight.

VolumeoccupiedbythegasattheS.T.P.=22.4litres

Massofthegas=1.6g.

Molecularweight=?

Terms involved in the problems are weight and volume of gas at S.T.P.

The standard relation connecting the above two terms is:

1.6×22.4

=16g

⇒Molecularweight=16.

Therefore, the molecular weight of the gas is 16 and the gas is methane (CH
