Question

If the volume of the original sample in Part A (P1 = 882 torr, Vi = 28.0 L) changes to 59.0 L, without a change inthe temperature or moles of gas molecules, what is the new pressure, P2?

Answer 1

Final pressure (P2) = 418.6 torr

Step-by-step explanation

Given:

Initial pressure (P1) = 882 torr

Initial volume (V1) = 28.0 L

Final volume (V2) = 59.0 L

Required: Final pressure (P2)

Solution

To solve this problem, use Boyles gas law:

P1V1 = P2V2

P2 = P1V1/V2

P2 = (882 torr x 28.0 L)/59.0 L

P2 = 418.6 torr
