PV=kT
since P and T are constant, so is V. That is,
V = (23 * 4/3 pi * 15^3)
A helium tank has a volume of 8.0 L. It contains enough helium to fill 23 circular balloons with a radius of 15 cm at a temperature of 25.0 C (room temperature). Assume that the pressure inside the balloons is 2.0 atm. What volume would all the gas in the tank occupy at 2.0 atm and a temperature of 25.0 oC (ie. when it is put into the balloons).
