Answer:
Final volume = 71 L
Explanation:
Since the question involves volume and pressure, we use Boyle's law which states that
P1V1 = P2V2;
Where P1 and P2 are initial and final pressure respectively, and V1 and V2 are initial and final volumes respectively.
P1 =50 atm, P2 = 14 atm, V1 = 20 L, V2 = ?
V2 = P1V1/P2
V2 = (50 * 20)/14
V2 = 71 L
