Answer to Question #120150 in General Chemistry for elijah

Question

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?

Answer 1

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
