(a) How many grams of oxygen does a person breathe in a day? (b) If this air is stored uncompressed in a cubical tank, how long is each side of the tank?
ANSWER:Solution 57P Step 1 : We need to find how many grams of oxygen a person breathe in a day On a average a human breathes 550 liters of pure oxygen in a day Converting this into grams 550 liters × 1gm = 550,000g 1000liters Hence on an average a human inhales 550,000 g of oxygen
