Answer 2

Answer:

8:1

Explanation:

Molecular mass of B=M

Molecular mass of A=2M

Let Root mean square velocity of B=C

Root means square velocity of A=2C

Pa/Pb=?

C =root PV/M

C^2=PV/M

P=C^2*M/V

So, Pb=C^2* M/V

Pa=2C^2*2M/V

Pa/Pb=(2C)^2*2M/V * V/C^2 *M

=4C^2*2M/V * V/C^2 *M

=8/1

Pa/Pb=8:1
