Solution Summary

This solution is provided in 165 words. It uses number of breaths per day and moles to find total volume of air breathed per day.

Solution Preview

First we need to find out the number of breaths per day:

(20 breaths/min) * (1440 min / d) = 28800 breaths / d

Next, we need to find the number of moles in an average breath from ...
