Question

a sample of carbon dioxide gas at a pressure of 1.10 atm and a temperature of 20.6 occupies a volume of 19.2 L. If the gas is allowed to expand at constant temperature to a volume of 24.3 L, the pressure of the gas sample will be ________ atm

Answer 1

0.87atm

Step-by-step explanation:

Given parameters:

Pressure of the gas = 1.1atm

Initial temperature = 20.6°C = 20.6 + 273 = 293.6K

Initial volume = 19.2L

New volume = 24.3L

Unknown:

New pressure = ?

Solution:

To solve this problem, we apply the Boyle's law equation:

P1V1 = P2V2

P and V are pressure and volume

1 and 2 are the initial and new states

1.1 x 19.2 = P2 x 24.3

P2 = 0.87atm
