Question

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?

A. 27. 43 kPa

B. 38. 62 kPa

C. 58. 73 kPa

D. 84. 11 kPa

Answer 1

Answer: A. 27.43 kPa

Step-by-step explanation:

Use the formula: PV/T = PV/T →

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

.0026P = .07144 →

P = 27.43 kPa :)
