A cylinder of compressed gas rolls off a boat and falls to the bottom of a lake. Eventually it rusts and the gas bubbles to the surface. A chemist collects a sample of the gas with the idea of trying to identify the gas. The wet gas collected occupies a volume of 275 mL at a pressure of 738 torr and temperature of 28.0oC. The vapor pressure of water at 28.0oC is 0.0372 atm.
1. Calculate the volume (L) that the gas occupies after it is dried (the water vapor removed) and stored at STP
The mass of the dry gas is 872 mg. A fragment of the tank indicates that the gas is a monoatomic element.
2. Write out the full name of the gas.
