Number of protons in oxygen atom: 8
Mass of one proton = 1.67262158 x 10-27 Kg
Mass of protons in one oxygen atom = 1.338097264 x 10-26 Kg
Mass of one neutron: 1.674927293 x 10-27 Kg
Mass of neutrons in one oxygen atom: 1.33994183 x 10-26 (for 8 neutrons)
Mass of one oxygen atom: 2.67803909 x 10-26 (protons + neutrons).
Now double the mass of one oxygen atom to get the mass of one molecule.
Therefore, mass of a single oxygen molecule is 5.35607818 x 10-26 kg.

How many atoms of carbon react with a molecule of oxygen to form a molecule of carbon monoxide?
there is one atom of oxygen in Carbon monoxide (CO) i.e. half molecule of oxygen.
What represent the mass of 1 molecule of SH2?
The mass of one molecule of SH2 is approximately 34.1 amu.
What does 'H2o' stand for?
H2O = Hydrogen two oxygen, (two hydrogen atoms and one oxygen atom = one water molecule) which is the chemical formula for water.
How is the molecular formula NO different from the molecular formula N2O?
A single nitrogen atom can be chemically reactive while a nitrogen molecule is relatively stable and tends to be faf more inert. A nitrogen molecule also has twice the mass of a nitrogen atom.
What is the mass of 1 molecule of nitrogen?
One molecule of nitrogen has a mass of approximately 4.65173 x 10-23 grams.
What is the formula of a molecule of oxygen?
The formula of an oxygen molecule is O2 (2 is a subscript but now WA doesn't permit to write a subscript).15.9994 g/mol is the molecular mass of oxygen. Formula mass is a sum of atomic mass of atoms in the molecule. In O2 there are two oxygen so it will be about 32g/mol
What is the mass of 0.05 moles of an oxygen molecule?
1.6g
How many molecules of oxygen are needed for the incomplete combustion of one molecule of methane?
Oxygen is NOT a PRODUCT (it is not produced) from the complete combustion of methane, it is a REACTANT (it is used in the reaction). The answer is therefore a mass of zero.
A molecule of water is composed of two atoms of hydrogen and one atom of oxygen if the atomic mass number of hydrogen is 1 and the molecular mass of water is 18 the atomic mass of oxygen must be?
16
An oxygen molecule O2 has twice the mass of a methane CH4 molecule In a planet's atmosphere at some particular temperature the average kinetic energy of an oxygen molecule is?
eggs
What new substance if one molecule of carbon combine with two molecule of oxygen?
It is sort of tricky question. One molecule of carbon can combine with only one molecule of oxygen. It can not combine with two molecules of oxygen. Incidentally one molecule of carbon is composed of one atom of carbon. One molecule of oxygen is composed of two atoms of oxygen.
The average relative mass of an ozone molecule is 48.0 you. An ozone molecule contains only oxygen atoms. What does this molecular weight indicate about the formula of the ozone molecule?
The ozone molecule (O3) has 3 oxygen atoms.
How many atoms does oxygen have in the molecule?
One molecule of Oxygen contains two atoms.
How much does one water molecule weight?
The mass of any molecule is equal to the sum of the Atomic Mass Units of all of its constituent atoms. Atomic Mass Unit values may be found on any Periodic Table. In this case, a water molecule consists of two Hydrogen atoms and one Oxygen atom. Hydrogen has a mass of approximately 1 AMU. Oxygen has a mass of approximately 16 AMU. Therefore, the mass of one molecule of water is approximately 18 AMU (or 18.01528 AMU exactly). What does this number mean? If you had exactly 6.022 x 10^23 molecules of water, it would weigh 18 grams.
Is liquid oxygen heavier than water?
A thing's heaviness is a measure of gravity's effect on its mass. Molecule for molecule, H2O (water) is heavier than O2 (oxygen); however, you are comparing two different molecules at two different pressures and densities. Oxygen, while lighter than water (molecule for molecule) at normal pressures, is much heavier when compressed to the point of condensation. Liquid oxygen has a weight of 1.141 g/ml, whereas water's weight is 1 g/ml. They are very close to the same weight, but liquid oxygen is almost 15% heavier.
What is a molar mass of atomic oxygen?
One oxygen atom by itself is written as O. Molecular oxygen is a molecule of two oxygen atoms that are covalently bonded. The atoms both attain the stable octet configuration.
How many atoms of carbon react with a molecule of oxygen to form a molecule of carbon monoxide?
there is one atom of oxygen in Carbon monoxide (CO) i.e. half molecule of oxygen.
