A) 8.5 atm
B) 10.8 atm
C) 11.7 atm
D) 17 atm
Correct Answer: C
Solution :
\[pV=\mu RT=\frac{m}{M}RT\] First case \[20\times V=\frac{m}{M}\times R\times 300\] ?(i) Second case \[p\,\times V=\frac{(m/2)}{M}\times R\times 350\] ?(ii) From Eqs. (i) and (ii), we get \[p\,=\frac{140}{12}=11.7\,atm\]You need to login to perform this action.
