Given that approximately 16 grams of oxygen contains a mole of oxygen atoms, the weight of an oxygen atom in grams can be solved by dividing by Avogadro's number. 16/(6.02 x 10^23) is equal to approximately 2.66 x 10 ^ -23 g, which is the approximate weight of an oxygen atom in grams.
Atomic Mass of oxygen is 15.9994.
The fun is, we simply say the atomic mass or weight of atom or molecule with some numerals.
The following unit is not gram or kilogram. That one is in a.m.u. a.m.u means atomic mass unit. One a.m.u equals to one twelfth of mass of carbon-12 isotope and that equals to 1.66 x 10 -27 kg.
So atomic mass of oxygen is 15.9994 x 1.66 x 10 -27 x 1000 gram.
The gram molecular mass for oxygen is 16.0 grams. (The molecular mass is simply another term for the atomic mass number in the Periodic Table of elements.)
The conventional value of the atomic weight of oxygen is 15,999; the equivalent in grams is 26,567.10-24 g.
The molar mass of oxygen gas (O2) is 32. If you look on the periodic table of elements the numbers underneath the symbols for the elements are their molar mass in grams
The weight of oxygen is about 16 amu.
The mass of the elements that are not oxygen equals 194.8g. The mass of oxygen is 230g - 194.8g = 35.2g of oxygen. Mass percent of oxygen = 35.2g O/230g x 100 = 15% O
Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.

Mass of hydrogen = 1 g/mol Mass of oxygen = 16 g/mol There are 2 hydrogen in H2O2 and 2 oxygen in H202, so (1x2) + (16x2) = 34 g/mol
wouldn't it be more than 1 g? i say this because the first substance that the oxygen would chemically combine to would have its own mass (1g), and once the oxygen combines to it, wouldn't the mass of the oxygen and the substance also combine, forming a new mass greater than 1 g?
The answer is 2,871 g oxygen.
This mass is 2,469 g.
The mass of the elements that are not oxygen equals 194.8g. The mass of oxygen is 230g - 194.8g = 35.2g of oxygen. Mass percent of oxygen = 35.2g O/230g x 100 = 15% O
The answer is 1,425 g oxygen.
The mass of 4.38 liters of oxygen is 6,259 g.
18 g or water will have 16 g of oxygen. So 9 g or water will have 8 g of oxygen.
The needed mass of oxygen is 16 g.
The molar mass of magnesium is 24.31 g/mol, while the molar mass of oxygen is 16 g/mol. To find the mass of 2.6 g of magnesium, you can divide 2.6 g by the molar mass of magnesium (24.31 g/mol) and multiply by Avogadro's number to find the number of moles. Similarly, you can do the same calculation for 1.6 g of oxygen and then sum up the molar masses to find the total mass.
The mass of 0,2 moles of oxygen gas is 6,4 g.
Atomic oxygen does not have a greater atomic mass than chlorine, nor does molecular oxygen. The atomic mass of chlorine is approximately 35 g/mol, while molecular (O2) oxygen has a molecular mass of 32 g/mol.
The mass fraction oxygen in water is 0.8881.m oxygen = ( 0.8881 ) ( 0.18 g H2O ) = 0.16 g oxygen in 0.18 g of H2O
