A) 1 : 2
B) 2
C) 1 : 4
D) 4
Correct Answer: B
Solution :
According to gas law \[PV=nRT\], \[n=\frac{PV}{RT}\] \[\frac{{{n}_{A}}}{{{n}_{B}}}=\frac{\frac{{{P}_{1}}{{V}_{1}}}{R{{T}_{1}}}}{\frac{{{P}_{2}}{{V}_{2}}}{R{{T}_{2}}}}\]; \[\frac{{{n}_{A}}}{{{n}_{B}}}=\frac{{{P}_{1}}{{V}_{1}}}{{{T}_{1}}}\times \frac{{{T}_{2}}}{{{P}_{2}}{{V}_{2}}}\] \[\frac{{{n}_{A}}}{{{n}_{B}}}=\frac{2P\times 2V}{2T}\times \frac{T}{PV}\]; \[\frac{{{n}_{A}}}{{{n}_{B}}}=\frac{2}{1}\]
