We can use Boyle's law to solve this problem, which states that the pressure of a gas is inversely proportional to its volume when temperature and amount are held constant. The formula is:
P1V1 = P2V2
Where:
P1 = 3.6 atm (initial pressure)
V1 = 95 mL (initial volume)
P2 = 0.85 atm (final pressure)
V2 = ? (final volume)
Substituting the given values, we get:
(3.6 atm)(95 mL) = (0.85 atm)(V2)
Simplifying, we get:
V2 = (3.6 atm)(95 mL) / (0.85 atm)
V2 = 404.7 mL
Therefore, the final volume of the gas is 404.7 mL.
