For the two gases,
${\text{P}}_{\text{A}}={\text{2P}}_{\text{B}}$

${\text{P}}_{\text{A}}{\text{V}}_{\text{A}}={\text{n}}_{\text{A}}{\text{RT}}_{\text{A}}\text{ and }{\text{P}}_{\text{B}}{\text{V}}_{\text{B}}={\text{n}}_{\text{B}}{\text{RT}}_{\text{B}}$

$\frac{{\text{n}}_{\text{A}}}{{\text{n}}_{\text{B}}}=\frac{\frac{{\text{P}}_{\text{A}}{\text{V}}_{\text{A}}}{{\text{RT}}_{\text{A}}}}{\frac{{\text{P}}_{\text{B}}{\text{V}}_{\text{B}}}{{\text{RT}}_{\text{B}}}}=\frac{\frac{2{\text{P}}_{\text{B}}\times 2{\text{V}}_{\text{B}}}{2{\text{T}}_{\text{B}}}}{\frac{{\text{P}}_{\text{B}}\times {\text{V}}_{\text{B}}}{{\text{T}}_{\text{B}}}}=2$

The number of molecules are also in the ratio 2 : 1.
