MCQ
If the ratio of masses of $\ce{SO_3}$ and $\ce{O_2}$ gases confined in a vessel is $1 : 1,$ then the ratio of their partial pressure would be :
- A$5 : 2$
- ✓$2 : 5$
- C$2 : 1$
- D$2 : 2$
✓
Answer
Correct option: B.
$2 : 5$
$\frac{1}{80}:\frac{1}{31} $
$\Rightarrow 2:5$ The ratio of number of moles and partial pressure is $2 : 5.$
$\Rightarrow 2:5$ The ratio of number of moles and partial pressure is $2 : 5.$
