States of Matter - Result Question 40

####40. Cyclopropane and oxygen at partial pressures 170 torr and 570 torr respectively are mixed in a gas cylinder. What is the ratio of the number of moles of cyclopropane to the number of moles of oxygen $(n C_{3} H_{6} / n O_{2})$ ?

[1996]

(a) $\frac{170 \times 42}{570 \times 32} = 0.39$

(b) $\frac{170}{42} / (\frac{170}{42} + \frac{570}{32}) \approx 0.19$

(d) $\frac{170}{570} = 0.30$

Show Answer

Solution:

(d) By Ideal gas equation $P_{1} V = n_{1} R T$

$n_{1} \propto P_{1}$ and $n_{2} \propto P_{2}$

$\frac{n_{1}}{n_{2}} = \frac{P_{1}}{P_{2}} \Rightarrow \frac{n_{1}}{n_{2}} = \frac{170}{570} = 0.30$
