each time you breath in, you take in 500 ml of air. the air you breath in is about 20% oxygen by volume. you breath roughly 8 times per minute when you sleep and lets assume you sleep for 8 hours in a night. given this information, how much mass would you lose over the course of 8 hour sleep period as a result of respiring out CO2 through respiration(disregard mass lost due to water loss)

Not enough info. How much CO2 is expelled during a regular breath?
