Question

If a gas occupies 22.4 L at 0.265 atm, then what will the pressure be in atmospheres if the gas occupies 35.52 L?

Assume all other variables are held constant.

A) 0.167 atm
B) 0.437 atm
C) 0.886 atm
D) 1.49 atm

Answer 1

A = 0.617atm

Step-by-step explanation:

V1 = 22.4L

P1 = 0.265atm

P2 = ?

V2 = 35.52L

To solve this question, we'll use Boyle's law which states that the volume of a fixed mass of gas is inversely proportional to its pressure provided that temperature remains constant.

Mathematically,

P1V1 = P2V2 = P3V3=...........=PnVn

P1V1 = P2V2

Solving for P2

P2 = (P1 * V1) / V2

P2 = (0.265 * 22.4) / 35.52

P2 = 0.1671atm

Pressure of the gas is 0.1671atm
