Question #120150
A sample of carbon dioxide occupies a volume of 3.50 liters at 125 kPa pressure>
What pressure would the gas exert if the volume was decreased to 2.00 liters?
What pressure would the gas exert if the volume was decreased to 2.00 liters?
Expert's answer
According to the combined ideal gas equation:
p1V1 = p2V2
where p1 - initial pressure, V1 - initial volume, p2 - final pressure, V2 - final volume.
From here:
p2 = p1V1 / V2 = 125 kPa × 3.50 L / 2.00 L = 219 kPa
Answer: 219 kPa
