A sample of carbon dioxide occupies 2.77 L at a pressure of 18.1 psi and a temperature of 56ºC. What pressure will the carbon dioxide exert if the volume is increased to 4.81 L while the temperature is held constant?

10.4psi

Explanation:

Since the problem involves pressure and volume at constant temperature, Boyle's law is the appropriate formula to use.

Boyle's law States that at a constant temperature, the volume of a given mass of a bass is inversely proportional to its pressure.

Using Boyle's law

P1v1 = p2v2

P1 is 18.1psi

V1 is 2.77L

P2 = ?

V2 is 4.81

Temperature is constant

P2 = P1v1 / v2

= 18.1 x 2.77 / 4.82

= 10.4psi
