WebAt standard temperature and pressure (0 Celsius and ~1 atmosphere pressure) oxygen has a density of 1.429 g/L, so 1,000 liters of oxygen would have a weight of 1,429 g. But for storage purposes oxygen cylinders are smaller volume, so the pressure is higher to be able to store more in less space. WebThe most prevalent version of these is Oxygen 16, which has 8 protons and 8 neutrons, for a total atomic mass of 16. O16 accounts for 97.765% of all oxygen atoms on Earth.
WebThe molar mass of a substance is the mass in grams of 1 mole of the substance. As shown in this video, we can obtain a substance's molar mass by summing the molar masses of its component atoms. We can then use the calculated molar mass to convert between mass and number of moles of the substance. Created by Sal Khan. WebNatural oxygen is a mixture of three stable isotopes: oxygen-16 (99.759 percent), oxygen-17 (0.037 percent), and oxygen-18 (0.204 percent). Several artificially prepared radioactive isotopes are known. The longest-lived, oxygen-15 (124-second half-life), has been used to study respiration in mammals.
