A clown at a birthday party has brought along a helium cylinder, with which he intends to fill balloons. When full, each balloon contains 0.00420 m^3 of helium at an absolute pressure of 1.20 x 10^5 Pa. The cylinder contains helium at an absolute pressure of 1.60 x 10^7 Pa and has a volume of 0.00220 m^3. The temperature of the helium in the tank and in the balloons is the same and remains constant. What is the maximum number of people who will get a balloon?

A cylinder 1.00m tall with inside diameter 0.120 m is used to hold propane gas(molar mass 44.1 g/mol) for use in a barbecue. It is initially filled in with gas until the gauge pressure is 1.30 x 10^6 Pa and the temperature is 22 degree Celsius. The temperature of the gas remains constant as it is partially emptied out of the tank, until the gauge pressure is 2.50 x 10^5 Pa. Calculate the mass of propane that has been used?
