A gas in a 50L container is transferred to a 200L container with a final pressure of 0.25 atm. What was the initial pressure of the gas in atm?

Respuesta :

We want to know the initial pressure, given:

V1 = 50L

V2 = 200L

P2 = 0.25 atm

P1 = ?

The following equation will be of use:

P1V1 = P2V2

P1 = (P2V2)/V1

P1 = (0.25atm x 200L)/50L

P1 = 1 atm
