Answer:
= 18.75 L
Step-by-step explanation:
Using the combined gas law;
P1V1/T2=P2V2/T2
Where; P1 is the initial pressure, 0.25 atm
V1 is the initial volume 300.0 L
T1 is the initial temperature, 400 K
P2 is 2 atm and
T2 is 200 K
Therefore;
(0.25 × 300)/400 = 2V2/200
V2 = (75 ×200)/(400×2)
= 18.75 L
