WebThe human lung consumes about 5-6 ml oxygen per minute at an esophageal temperature of 28 degrees C. Prebypass whole-body oxygen consumption measured at nearly normothermic conditions was 198 +/- 28 ml/min. Mean lung and whole-body respiratory quotients were similar (0.84 and 0.77, respectively). WebOne mole of any substance contains 6.02 x 1023 particles. Air is about 21% oxygen making 1 liter of air to be about 0.21 liters of oxygen. To find out how many moles that represents=0.21 / 22.4. Then use Avogadro's number 6.02 x 10^23 atoms/mole. 1 L = 5.64e21 atoms or 2.82e21 molecules/L. 6L/breath => 1.69e22 molecules/breath.
Web27 jan. 2011 · Numerous sources give the number of molecules of air per liter, at STP, as approximately 2.5E22. A liter contains 1E3 cubic centimeters, and a cubic meter contains 1E6 cubic centimeters. Thus a cubic meter contains 1E3 liters, and the number of molecules in a cubic meter is approximately 2.5E25.
