A sample of unknown pressure occupies 0. 776L at a temperature of 298K. The sample of gas is then tested under known conditions and has a pressure of 32. 6 kPa and occupies 0. 664L at 303K. What was the original pressure of the gas?

Answer: 27.43 kPa

Step-by-step explanation:

Use PV / T = PV / T →

P(.776) / (298) = (32.6)(.664) / (303) →

Cross Multiply to get: 235.128P = 6450.6272 →

Divide to get: P = 27.43 kPa :)
