Explanation Given Info: The mass of carbon dioxide exhaled by a single astronaut in each day is 1.09 Kg , the volume of the tank is 150 L and the temperature is − 40.0 ° C . Formula to calculate the final pressure is, P V = ( m M ) R T (1) Here, m is the molecular mass of the substance. M is the molecular weight of the substance. R is the gas constant. T is the temperature. V is the volume. It is given in the problem that the methane generated in the respiration recycling of three astronaut during one week of flight is stored in a tank of volume 150 L . The mass of CO 2 released by the three astronauts in one week is, m = ( 1.09 Kg ) ( 3 ) ( 7 ) = 22.89 Kg The molar mass of the CO 2 is 44 × 10 − 3 Kg / mol Rearrange the equation (1) for P . P = ( m M ) R T V Substitute 22.89 Kg for m , 150 L for V , 8

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 1,08 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 165-L tank at -45.0°C, what is the final pressure in the tank?
