A cylinder containing 11.0L of helium gas at a pressure of 165atm is to be used to fill birthday balloons to a volume of 2.50L per balloon and at a pressure of 1.10atm. What is the maximum number of balloons that can be inflated at a constant temperature? (remember that 11.0L of gas at 1.10atm will remain in the "exhausted" cylinder.)
I'm stuck and I keep confusing myself. This is what I got using Boyle's law:
P1=165atm P2=1.10atm
V1=11.0L V2=2.50L
P1V1=1815 P2V2= 2.75
To get the number of balloons, do I divide 1815 by 2.75 to get 660?
