Private answer

Initial pressure in the 50.0 L bulb is 2 atm

Explanation:

PiVi = PfVf

where:

Pi = initial pressure = ?

Vi = initial volume = 50 L

Pf = final pressure = 2.20 atm

Vf = final volume = (50L + 250L) = 300 L

Pi * 50 = (2.2 * 300)

Pi = (2.2 * 300) / 50

Pi = 13.2 atm

Initial pressure in the 50.0 L bulb is 13.2 atm
