Question

a sample of methane gas at a pressure of 0.727 atm and a temperature of 26.9 occupies a volume of 726 ml. if the gas is allowed to expand at constant temperature until its pressure is 0.412 atm, the volume of the gas sample will be _ mL

Answer 1

1280L

Step-by-step explanation:

Given parameters:

Initial pressure = 0.727atm

Temperature = 26.9°C

Initial volume = 726mL = 0.726L

New pressure = 0.412atm

Unknown:

New volume of the gas sample = ?

Solution:

To solve this problem, we apply boyles law;

P1V1 = P2V2

P and V are pressure and temperature

1 and 2 are initial and new state

0.727 x 0.726 = 0.412 x V2

V2 = 1.28mL = 1280L
