A sample of oxygen gas occupies 3.60 liters at a pressure of 1.00 atm. If the temperature is held constant, what will be the volume of the oxygen gas at a pressure of 2.50 atm?

0.694 L

1.44 L

4.35 L

9.20 L

Answer;

= 1.44 L

Explanation;

Boyle's law states that the volume of a fixed mass of a gas is inversely proportional to its pressure at a constant temperature.

Mathematically;

P α 1/V

PV = constant

Thus, P1V1 = P2V2

P1 = 1.00 atm, V1 = 3.60 liters, V2 = ?, P2 = 2.50 atm

V2 = P1V1/P2

= (1 * 3.6) / 2.5

= 1.44 L
