Humans and other mammals breathe in oxygen from the air for respiration.
At the top of Mt Everest, assume the atmospheric pressure is 0.500 atm and the temperature is -35.0°C. Assume that the volume of one breath is still 0.500 L. Calculate the number of moles of air in one breath at the top of Mt Everest.
Remember the gas constant, R, is 0.08206 L'atm/mol-K.
