we need to determine the volume of the gas in the cylinder when the pressure is decreased to 1.0atm
write down the known and unknown quantities
P1 = 170.0 atm
V1 = 14.50 L
P2 = 1.0 atm
V2 = ?
Use Boyle’s law to find the unknown volume
P1V1 = P2V2
V2 = “frac{P_1V_1}{P_2}”
V2 = “frac{170.0atmu00d714.50L}{1.0atm}”
V2 = 170×14.50 L
V2 = 2465 L
Calculate the number of ballons that can be filled up by dividing the total volume of gas at 1.0 atm by the volume of a single ballon
Nballoon = “frac{V_2}{V_balloon}”
Nballoon = “frac{2465}{2.5}”
Nballoon = 986 ballons
Nballons = 0.9×103 balloons
