I am blowing up balloons for my daughter’s birthday party
I am blowing up balloons for my daughter’s birthday party. I want them to float while tethered to a table, but I only have a little bit of helium left in the tank. So I can only use a little in each balloon, and I will fill the rest of the balloon with oxygen and nitrogen (I thought it would be much more entertaining to have elemental oxygen in the balloons around all those birthday candles!). Suppose that in each balloon, the oxygen has a pressure of 0.292 atm and the nitrogen has a pressure of 0.587 atm. If the total pressure inside the cylinder is 1.01 atm, what is the pressure that is due to the helium?
A.0.131 atm
B.1.01 atm
C.0.879 atm
D.0.722 atm
