Answer to Question #150988 in General Chemistry for Ramsha Zarmeen

Question

1800ml of oxygen gas exerts 2atm pressure At constant t it expands at 2700ml calculate its final pressure

Answer 1

Solution:

1) Since temperature is constant:

$P_{initial}V_{initial}=P_{final}V_{final}$

$P_{final}= \dfrac{P_{initial}V_{initial}}{V_{final}}$

$P_{final}=\; \dfrac{202.65\:KPa\;*\;1.8L}{2.7L}=\;135\;KPa$

$Answer: 135\;KPa$
