Ideal Gas Law - example

Calculations:

• 1 mole of O2 gives

6x1023 molecules/mole* 6.4x10-19J/molecule = 400,000 Joules/mole of energy if completely used.

• 1 mole of O2 requires 5 moles of air.

• Since the metabolic rate/person is about 100 Watts = 100 Joules/sec, 5 moles of air will give about 4,000 sec. of O2 .
