Asked by Eric
You have a 22L cylinder of helium at a pressure of 150atm and a temperature of 31C. How many ballons can you fill, each with a volume of 5.0L, on a day when the atmospheric pressure is 755mmHg and the temperature is 22C?

Use PV = nRT to calculate n, number of moles in the cylinder of He.
Plug n into PV=nRT under the new conditions to determine the volume at the new conditions. The number balloons = new volume x (1 balloon/5.0L) = ??
