Original Note:
The PLSS backpack on the Apollo missions did not hold “22 hours of oxygen”. The initial version for Apollo 11 to 14 had 4 hours of oxygen. On Apollo 15 to 17 this was doubled to 8 hours. The amount of oxygen needed is about 160 grams per hour, or 1.3kg for 8 hours. https://www.nasa.gov/wp-content/uploads/static/history/alsj/ALSJ-FlightPLSS.pdf
