A clown at a birthday party has brought along a heliumcylinder, with which he intends to fill balloons. When full, eachballoon contains 0.00400 m3 of helium at an absolutepressure of 1.20 x 105 Pa. The cylinder contains heliumat an absolute pressure of 2.00 x 107 Pa and has avolume of 0.00230 m3. The temperature of the helium inthe tank and in the balloons is the same and remains constant. What is the maximum number of people who will get a balloon?
