Question
A 10.0 L vessel contains gas X at a pressure of 300 torr. A 4.0L vessel contains gas Y at a pressure of 450 torr. The two gassesare forced into a third 3.0 L vessel which is initially empty.Calculate the resulting total pressure in the third vessel (intorr). Assume the temperature remains constant and the gases behaveideally.

Explanation / Answer
volume V1 = 10.0 L pressure P1 =300 torr volume V2 = 4.0 L pressure P2=450 torr volume V3 = 3.0L pressure P3 = ? at constant temperature P3=(P1V1+P2V2) / V3 = (10.0L*300torr + 4.0 L * 450 torr ) / 3.0 = 1600 torr Total pressure inthe third vessel P3 = 1600 torr volume V2 = 4.0 L pressure P2=450 torr volume V3 = 3.0L pressure P3 = ? at constant temperature P3=(P1V1+P2V2) / V3 = (10.0L*300torr + 4.0 L * 450 torr ) / 3.0 = 1600 torr Total pressure inthe third vessel P3 = 1600 torrRelated Questions
