Pressure of 1 g o

Answer :

For ideal gas A, the ideal gas equation is given by,

PaV = naRT

Where, Pa and na represent the pressure and number of moles of gas A.

For ideal gas B, the ideal gas equation is given by,

PbV = nbRT

Where,Pa and nb represent the pressure and number of moles of gas B.

[V and T are constants for gases A and B]

Therefore, we have,

Where, Ma and Mb are the molecular masses of gases A and B respectively.

Now, we have

Substituting the values

ma = 1 g

Pa = 2 bar

mb = 2 g

Pb = 1 bar.


(Since total pressure is 3 bar)

Substituting these values in equation we have

Thus, a relationship between the molecular masses of A and B is given by

4Ma = Mb
