Two vessels separately contain two ideal gases $\text{A}$ and $\text{B}$ at the same temperature, the pressure of $\mathrm{A}$ being twice that of $\text{B}$. Under such conditions, the density of $\text{A}$ is found to be $\text{1.5}$ times the density of $\text{B}$. The ratio of molecular weights of $\text{A}$ and $\text{B}$ is

• Correct answer
  A

  $\frac{3}{4}$
• B

  $2$
• C

  $\frac{1}{2}$
• D

  $\frac{2}{3}$

Hence, the correct answer is option: 'A'.
