Find final pressure of gas - Boyles Law - Chemistry problem solver

A gas has a pressure of 1.26 atm (initial pressure) and has a volume of 7.40 L (initial volume). If the gas is compressed to a volume of 2.93 L (final volume), what will its pressure (final pressure) ?


initial pressure = 1.26
initial volume = 7.4
final volume = 2.93
P2 =  ( P1 * V1 ) / V2
final pressure = ( 1.26 * 7.4 ) / 2.93
final pressure = 3.1823
So the final pressure is 3.1823

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
