Step 1
First, we need to find out how many liters of air the adult inhales per year. We know that the adult inhales 355 L of air per hour. There are 24 hours in a day and 365 days in a year, so: Liters of air per year = 355 L/hour * 24 hours/day * 365 days/year = Show more…

Air consists of molecules of several types, with an average molar mass of 28.95 g. About how many molecules does an adult who inhales $0.50 \mathrm{~L}$ of air at sea level take in?
A healthy human adult inhales on average about 500 ml of air with each breath. How many air molecules are present in this volume assuming a body temperature of 37°C and 1.1 atm?
