Question

density of gas A is twice that of B molecular mass of A is half molecular mass of B ratio of partial pressure of A and B​

Answer 1

4

Explanation:

According to Ideal gas equation

PV=nRT

n=Mm

PV=MmRTP=Vm×MRTP=d× MRT

As R and T are constant

PA=MAdAPB=MBdB

Given MA=21MBdA=2dB

PBPA=MAdBdAMB

Putting the value of 

Answer 2

Explanation:

Let density of gas B be d.

density of gas A = 3d

and let molecular weight of A be M.

molecular weight of B = 2M

Since, R is gas constant and T is same for both gases, so
