As early as 1938, the use of NaOH was suggested as a means of removing CO2 from the cabin of a spacecraft according to the following reaction : NaOH+CO2 -> Na2CO3 + H2O
As early as 1938, the use of NaOH was suggested as a means of removing CO2 from the cabin of a spacecraft according to the following reaction : NaOH+CO2 -> Na2CO3 + H2O. If the average human body discharges 925. 0 g of CO2 per day how many moles of NaOH are needed each day for eacch person in the spacecraft?
