A closed gas system initially has volume and temperature of 5.43 L and 831 K with the pressure unknown. If the same closed system has values of 0.811 atm, 7.31 L and 501 K,

Question

what was the initial pressure in atm rounded to the nearest hundredths place.

Answer 1

Hello, Dylan,

I just answered a similar question, so please review that one for more details.

Use P1V1/T1 = P2V2/T2. In this case we want to calculate P1, so rearrange the equation to:

P1 = T1P2V2/T2V1

and now enter the data. Round your answer to the nearest hundredths place.
