Answer:
0.978L
Explanation:
Using Boyle's law equation as follows;
P1V1 = P2V2
Where;
P1 = initial pressure (atm)
P2 = final pressure (atm)
V1 = initial volume (L)
V2 = final volume (L)
According to the provided information,
P1 = 1.49 atm
V1 = 5.00 liters
P2 = 7.62 atm
V2 = ?
Using P1V1 = P2V2
1.49 × 5 = 7.62 × V2
7.45 = 7.62V2
V2 = 7.45/7.62
V2 = 0.978L
