A) \[\frac{3}{4}\]
B) \[2~\]
C) \[\frac{1}{2}\]
D) \[\frac{2}{3}\]
Correct Answer: A
Solution :
[a] From \[\,PV=nRT\] \[{{P}_{A}}=\frac{{{\rho }_{A}}{{M}_{A}}}{RT}\text{ and }{{P}_{B}}=\frac{{{\rho }_{B}}{{M}_{B}}}{RT}\] From question, \[\frac{{{P}_{A}}}{{{P}_{B}}}=\frac{{{\rho }_{A}}}{{{\rho }_{B}}}\frac{M{{ & }_{A}}}{{{M}_{B}}}=2\frac{M{{ & }_{A}}}{{{M}_{B}}}=\frac{3}{2}\] \[\text{So, }\frac{M{{ & }_{A}}}{{{M}_{B}}}=\frac{3}{4}\]
