a bulb of unknown volume V contains a gas at 1 atm pressure. this bulb was connected to another evacuated bulb of volume 0.5 L through a stop cock. when the stop cock was opened, the pressure at each bulb becomes 7.58*10 raise to power 5 Pa while the temperature remained constant. calculate V in litres.

Expert Answer
1 atm = 101325 Pa
P1V1 = P2V2
101325 x V = 7.58 x 104 x (V + 0.5)
101325V - 75800V = 37900
V = 37900/25525
V = 1.48 L
