A sample of a gas (5.0 mol)at 1.0 atm is expanded at constant temperature from 10.0 L to 15 L. The final pressure is _______ atm.

Answer 1

P1V1 = P2V2

Answer 2

.67

Answer 3

7.5 atm

Answer 4

7.5

Answer 5

P1V1=P2V2
- P1 = 1.0 atm
- V1 = 10L
- V2 = 15L
- P2 = ?
(1.0 atm)(10L)=(P2)(15L)
10=(P2)(15L)
P2=10/15
P2 = 0.67 atm
