A sample of carbon dioxide gas occupies a volume 3.50Lat 125kPa pressure. What pressure would exert if the volume was decreased to 2.00L at constant temperature

Using the ideal gas law equation, we can determine the new pressure of the carbon dioxide gas.

PV = nRT

Where:
P = pressure
V = volume
n = number of moles
R = ideal gas constant
T = temperature

Since the temperature is constant, we can set up a ratio of the initial pressure and volume to the final pressure and volume:

P1V1 = P2V2

(125 kPa)(3.50 L) = P2(2.00 L)

P2 = (125 kPa)(3.50 L) / 2.00 L
P2 = 218.75 kPa

Therefore, if the volume of the carbon dioxide gas is decreased to 2.00 L at constant temperature, the pressure exerted would be 218.75 kPa.
