A gas system has initial pressure and volume of 2790 torr and 14.32 L. If the volume changes to 16200 mL, what will the new pressure be in atm? (1 atm=760 torr)

Answer 1

Hello, Dylan,

Use P1V1/T1 = P2V2/T2. It makes no mention of the temperature, so assume no change and the two temperatures cancel out. Since we want P2, rearrange the resulting equation to P2 = P1V1/V2. Use 4 sig figs to get 2466 torr, and then divide that by (760 torr/1 atm) to get atmospheres.
