Question

no. of molecules of air inhaled by human being per breath

Answer 1

Answer:

A single mole of any gas at body temperature and atmospheric pressure has a volume of about 25.4 litres. The volume of air breathed in or out in the average human breath is about 1 litre. So we can assume that Leonardo da Vinci, in one breath, breathed out about 2.4 × 1022 molecules

Answer 2

Answer:

Using Avogadro's number (6.02×10²³) and the volume of 1 mole of gas at STP (24×10ˉ³m³) we can arrive at an estimate for the number of molecules in a single breath. This gives us a value of 1.25×10²² molecules.
