A) \[\frac{1}{2}\]
B) \[\frac{1}{4}\]
C) 2
D) 4
Correct Answer: A
Solution :
Number of moles of oxygen \[=\frac{8}{32}=\frac{1}{4}\] Number of moles of nitrogen \[=\frac{7}{28}=\frac{1}{4}\] Therefore, total number of moles in mixture of two gases, \[n=\frac{1}{4}+\frac{1}{4}=\frac{1}{2}\]You need to login to perform this action.
