Heliox is a breathing gas mixture of helium (He) and oxygen (O2). It is used as a medical treatment for patients with difficulty breathing because mixture generates less resistance than atmospheric air when passing through the airways of the lungs, and thus requires less effort by a patient to breathe in and out of the lungs. It is also used as a breathing gas diluent for deep ambient pressure diving as it is not narcotic at high pressure, and for its low work of breathing. Web25 aug. 2024 · The molar mass of sodium chloride is known; it is 58.44 g mol −1. If we have to measure one mole of sodium chloride, there is no instrument that can directly measures it. But we know 58.44 g of sodium chloride is equivalent to one mole of it. So, we measure 58.44 g of NaCl with a weight scale, which is equivalent to one of 58.44 g.
