Final volume of gas filled in a baloon - Boyles Law - Chemistry problem solver

A balloon has a volume (initial volume) of 2.0 L. It is filled with a gas at 3 atm (initial pressure). Pressure is reduced to 0.5 atm (final pressure) without a change in temperature. What will be the volume (final volume) of the balloon?


initial volume = 2
initial pressure = 3
final pressure = 0.5
V2 =  ( P1 * V1 ) / P2
final volume = ( 3 * 2 ) / 0.5
final volume = 12
So the final volume is 12

Boyles Law :

When the pressure of the gas increases the volume of the gas decreases at constant pressure.

Boyles law Formulas :

P1 =  ( P2 * V2 ) / V1

V1 =  ( P2 * V2 ) / P1

P2 =  ( P1 * V1 ) / V2

V2 =  ( P1 * V1 ) / P2


where,

P1 = initial pressure
P2 = final pressure
V1 = initial volume
V2 = final volume
