Long-term space missions require reclamation of the oxygen in the carbon dioxide exhaled by the crew. In one method of reclamation, 1.00 mol of carbon dioxide produces 1.00 mol of oxygen, with 1.00 mol of methane as a by-product. The methane is stored in a tank under pressure and is available to control the attitude of the spacecraft by controlled venting. A single astronaut exhales 1.14 kg of carbon dioxide each day. If the methane generated in the recycling of three astronauts' respiration during one week of flight is stored in an originally empty 170-L tank at 48.0C, what is the final pressure in the tank?

Answer rating: 100% (QA)

To determine the final pressure in the tank we can use the ideal gas law which states PV nRT where P is the pressure V is the volume n is the number of moles R is the ideal gas constant and T is the t... View the full answer
