Answer:
2.31 atm
Explanation:
Use the combined gas law:
P1V1/T1 = P2V2/T2
where P, V, and T are pressure (P), volume (V), and temperature (T). P1, V1, and T1 are the initial states and P2, V2, and T2 are the final states. Temperature must be in Kelvin.
We are given:
V1 = 3.0L
P1 = 1.0 atm
V2 = 1.3, and
temperature is unknown, but held constant: T2 = T1
Rearrange P1V1/T1 = P2V2/T2 for the unknown, P2:
P2 = P1(V1/V2)(T2/T1)
Enter the data:
P2 = (1.0atm)((3.0L)/(1.3L))(T1/T1) [The temperatures cancel]
P2 = (1.0atm)((3.0L)/(1.3L)
P2 = (1.0atm)(2.31)
P2 = 2.31 atm
