A) 3/2
B) 2
C) 1
D) 3
Correct Answer: B
Solution :
For a given mixture of gases, \[({{n}_{1}}+{{n}_{2}})/(\lambda -1)={{n}_{1}}/({{Y}_{1}}-1)+{{n}_{2}}/({{Y}_{2}}-1)\] Put \[{{n}_{1}}=2,Y=3/2,{{Y}_{1}}=5/3,{{Y}_{2}}=7/5\] solving the required equation as \[(2+n)/(3/2-1)=2/(5/3-1)+n/(7/5-1)\] \[n=2\]You need to login to perform this action.
