Answer 2

Answer:

Answer : 6

Explanation:

From Ideal Gas Equation,

                    PV = nRT

                    PV = (m/M) RT ; m = mass , M = Molecular Mass

                    PM = (m/V) RT

                    PM = dRT         ; d = density

                    P = (d/M) RT

             So , P is directly proportional to (d/M)

Now, given ,

dx = 3dy

So , dx / dy = 3

My = 2 My

So, Mx / My = 1/2

Now,

$Px / Py = (dx/dy)/(Mx/My)$

$Px/Py = 3/(1/2)\\Px/Py = 6$
