A) 60
B) 40
C) 6
D) 4
Correct Answer: A
Solution :
[a] \[\underset{a}{\mathop{{{N}_{2}}}}\,+\underset{a}{\mathop{{{O}_{2}}}}\,\to \underset{2a}{\mathop{2NO}}\,\] |
\[CO+\frac{1}{2}{{O}_{2}}\to C{{O}_{2}}\] |
\[\left( 10-a \right)\text{ }\frac{(10-a)}{2}\,\,~\left( 10-a \right)\] |
\[a+\frac{(10-a)}{2}=7\] |
\[\therefore \text{ }a=4\] |
volume of CO = 6 mL |
Mole % of \[CO=~\frac{6\times 100}{10}~=60\] |
