We are asked to calculate the original pressure of the system.
Boyle's law states the relationship between pressure and volume of gases. It states that pressure of gas is inversely proportional to volume of gases at constant temperature.
P1V1 = P2V2
parameters for the first instance on the left side and parameters for the second instance are on the right side of the equation
P - original pressure
P x 365.2 mL = 241.3 Torr x 478.2 mL
P = 316.0 Torr
