A) 3.5
B) 3.8
C) 3.95
D) 4.25
Correct Answer: B
Solution :
\[V={{V}_{1}}+{{V}_{2}}\] \[\frac{nRT}{P}=\frac{{{n}_{1}}R{{T}_{1}}}{{{P}_{1}}}+\frac{{{n}_{2}}R{{T}_{2}}}{{{P}_{2}}}\] \[\frac{2R342}{P}\,\,=\,\,\frac{0.5R300}{2}\,\,+\,\,\frac{1.5R\times 350}{5}\] \[\frac{684}{P}\,\,=\,\,75+105\] \[P\,\,=\,\frac{684}{180}\,\,=\,3.8\]You need to login to perform this action.
