A gas in a sealed container had its volume increased from 12.1 liters to 21.1 liters.
ArbitrLikvidat [17]

Answer:

The answer to your question is   P2 = 170.9 torr

Explanation:

Data

Volume 1 = 12.1 l                                Volume 2 = 21.1 l

Temperature 1 = 241 °K                      Temperature 2 = 298°K

Pressure 1 = 546 torr                           Pressure 2 = ?

Process

To solve this problem use the combined gas law.

                P1V1/T1 = P2V2/T2

-Solve for P2

                P2 = T1V1T2 / T1V2

-Substitution

                P2 = (241 x 12.1 x 298) / (241 x 21.1)

-Simplification

                P2 = 868997.8 / 5085.1

-Result

                P2 = 170.9 torr
