WebStep 1: Molar mass of oxygen ( O 2): The molar mass of oxygen = 16 × 2 = 32 gmol - 1. It means that 1 mole of oxygen has mass = 32 g Step 2: Mass of one molecule of oxygen: 1 mole of oxygen = 6. 022 × 10 23 molecules of oxygen The mass of 6. 022 × 10 23 molecules of oxygen = 32 g WebThe oxygen passes into the atmosphere and the hydrogen joins with carbon dioxide to produce biomass. When living things need energy they take in oxygen for respiration. The oxygen returns to the atmosphere in the form of carbon dioxide. Oxygen gas is fairly soluble in water, which makes aerobic life in rivers, lakes and oceans possible.

WebIdeal gasses are much more easy to understand than non-ideal gasses. For ideal gasses, the density of the gas (the weight for a given volume--basically the heaviness) is directly proportional to the mass of an individual molecule. For oxygen, a molecule consists of two oxygen atoms, and has a weight of 2 x 16 = 32. Triatomic oxygen (ozone, O3) is a very reactive allotrope of oxygen that is a pale blue gas at standard temperature and pressure. Liquid and solid O3 have a deeper blue color than ordinary O2, and they are unstable and explosive. In its gas phase, ozone is destructive to materials like rubber and fabric and is damaging to lung tissue. Traces of it can be detected as a pungent, chlorine-like smell, coming from electric motors, laser printers, and photocopiers, as it is formed …

It is a common misconception that an oxygen molecule, O2, is “larger” than a nitrogen molecule, N2. This notion arises from misunderstanding molar mass and conflating mass with volume.
WebMay 7, 2024 · The other process is gas exchange. This is the biochemical process in which oxygen diffuses out of the air and into the blood while carbon dioxide and other waste gases diffuse out of the blood and into the air. All of the organs of the respiratory system are involved in breathing, but only the lungs are involved in gas exchange.
