How many moles of gas are contained in a typical human breath that takes in 0.5L of air at 1.0 atm of pressure and 37 degrees Celsius? Please enter your answer in numerical form (for example instead of writing "one" type the number "1" [do not include quotation marks]). Also, please do not write the unit. In this problem, do not write out the unit "mol" beside the numerical answer. Write ONLY the numerical answer. Hint: Be sure to remember to convert the temperature to Kelvin.
