Answer:
10.4psi
Explanation:
Since the problem involves pressure and volume at constant temperature, Boyle's law is the appropriate formula to use.
Boyle's law States that at a constant temperature, the volume of a given mass of a bass is inversely proportional to its pressure.
Using Boyle's law
P1v1 = p2v2
P1 is 18.1psi
V1 is 2.77L
P2 =?
V2 is 4.81
Temperature is constant
P2 =P1v1/ v2
= 18.1 x 2.77 / 4.82
= 10.4psi
