- Calculate the average atomic mass of oxygen. Solution: ((15.994915*99.757) + (16.999132*0.038) + (17.999160*0.205))/100 = 15.999405 . Using our equation for determining average atomic mass, we see that the average atomic mass for oxygen is 15.999405 amu. If we check the periodic table, we will see that our average atomic mass is the same as the atomic mass indicated on the element oxygen. ×

- The mole of any element is simply its atomic weight. Thus, one mole of carbon is 12.01 grams because that is the atomic weight of carbon. In one mole of oxygen there is 16.00 grams because that is the atomic weight of oxygen.If you are asked to find out how many moles there are in a given mass you use the equation: number of moles = mass (given)/atomic weight.he mole of any element is simply its atomic weight. Thus, one mole of carbon is 12.01 grams because that is the atomic weight of carbon. In one mole of oxygen there is 16.00 grams because that is the atomic weight of oxygen.

What Is the Molar Mass of Sodium Nitrate? The molar mass of NaNO3 is equal to the sum of the molar masses of all the elements that make up one molecule of the compound. To find the masses of these elements, consult the Periodic Table. The molar masses of Sodium, Nitrogen and Oxygen are 22.99, 14.01 and 16 grams, respectively. To find the molar mass of NaNO3, add the molar masses of all the atoms used in the compound 22.99g + 14.01g + (3 x16g), which is equal to 85g.

Humans can survive much lower blood oxygen levels than thought The average arterial oxygen level of his team was 3.28 kilopascals, or kPa, with the lowest value 2.55kPa. The normal value in humans is 12-14kPa. A patient below 8kPa would be considered critically low, said Grocott.

Density The average density of an object equals its total mass divided by its total volume. A denser object (such as iron) will have less volume than an equal mass of some less dense substance (such as water). The SI unit of density is the kilogram per cubic meter (kg·m-3). where.

Finding density of oxygen? Ok. Density is mass/ volume. To find mass, i'm not quite sure, but i'll assume its one mole, which equals 32 grams. For volume, use the ideal gas law. Volume x pressure = moles x R x temperature. V x 2.3=1 x .0821(R for atmospheres) x 305K V = 10.89L So... 32g/10.89L=2.94g/L Assuming the amount of oxygen is one mole.

Some energy units, definitions and conversions Carbon has an atomic weight of 12, the atomic weight of oxygen is 16. Therefore, when one kg of carbon combines with oxygen we have 12 mass units of carbon and 32 units of oxygen being converted into 44 units (12 + 16 + 16 = 44) of carbon dioxide. 1kg of carbon becomes 1 x 44/12 = 3.7kg (approximately) of CO2.

What Is Ear Pain? An earache may affect one or both ears, but the majority of the time it is in one ear. Read more. Earaches usually occur in children, but they can occur in adults as well. An earache may affect one or both ears, but the majority of the time it is in one ear. It may be constant or come and go, and the pain may be dull, sharp, or burning. If you have an ear infection, fever and temporary hearing loss may occur.

How do you determine the mass of one mole of oxygen gas? The specific number of molecules in one gram-mole of a substance, defined as the molecular weight in grams, is 6.022140857 × 1023, a quantity called Avogadro’s number, or the Avogadro constant. For example, the molecular weight of oxygen is 32.00, so that one gram-mole of oxygen has a mass of 32.00 grams and contains 6.022140857 × 1023 molecules.

- We then take the atomic weight of the atoms from the periodic table. For hydrogen, the atomic weight is 1.00794, and for oxygen it is 15.9994. Since there are 2 hydrogens in the molecule, the total weight of hydrogen in water is 2 times 1.00794, or 2.01588. There is only 1 oxygen, so the total weight of oxygen is 15.9994. Finally, we add up the weights of all the atoms to get the total molecular weight of water, 18.0153 grams per mole.
