The enclosed cabin of a submarine has a volume of 2.4 x 105 liters, a temperature of 312 K, and a pressure of 116 kPa. As people in the cabin
breathe, carbon dioxide gas, CO2(g), can build up to unsafe levels. Air in the
cabin becomes unsafe to breathe when the mass of CO2(g) in this cabin
exceeds 2156 grams.
Determine the number of moles of CO2(g) in the submarine cabin at which the
air becomes unsafe to breathe. The gram-formula mass of CO2 is 44.0 g/mol.
