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.)
Hydrogen has a molecular mass of 1 where as an oxygen atom has a molecular mass of 16 so oxygen is heavier than hydrogen
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.
Atomic mass of sodium is 23. The atomic mass of oxygen is 16. Therefore the molecular mass of sodium oxide is 23x2+16=62u.The atomic mass of oxygen is 16. Atomic mass of sodium is 23. Therefore the molecular mass of the given compound is 62 grams per mole.
There are three oxygen atoms in an ozone molecule. The RAM of oxygen is 16. Therefore the molecular mass of ozone is 16x3=48u.
The molecular mass of CO is 28. The carbon percentage by mass is ~43%. Hence the oxygen percentage by mass is ~57%.
Since each water molecular contains two hydrogen atoms, the atomic mass of oxygen is 18 - 2 = 16.
I assume you mean the molecular mass. The diatomic oxygen's molecular mass is 32g/mol. The element is 16 (or 15.9994 to be exact) g/mol
Codeine : C18H21NO3Molecular Mass: 299Mass of oxygen present: 3 X 16 = 48Mass% of Oxygen : 48/299 * 100 = 16 %
Atomic mass of iron is 56u. Atomic mass of oxygen is 16u. molecular mass of Iron(III) Oxide is 2x56+3x16=160u.
Molecular oxygen will effuse faster because: Molar Mass of O2: 32g Atomic Mass of Ar: 40g
An oxygen molecule is diatomic ie. it has two atoms (O2). As the atomic mass of a single oxygen atom is indeed 16, the molecular mass of O2 is (2 x 16) = 32.
Molar mass of it is 32gmol-1. It is twice than an atom.
You need to be a bit more specific with your question. I presume you mean the molecular mass of water? This can be worked out from your periodic table. We know the atomic mass of hydrogen is ~1, and oxygen is ~ 16. The molecular formula for water is H2O, therefore we have (2*1) for the Hydrogen, + (1 * 16) for the oxygen. Therefore the molecular mass of water is ~ 18. Note: I rounded the molecular values off to 1 and 16 for the purposes of a simple example. The real molecular mass of hydrogen is 1.00794 and for oxygen is 15.9949. If you have to use more significant figures, use these numbers.
Water molecules are composed from hydrogen and oxygen. Their atomic masses are 1 and 16 respectively. The molecular mass of water is 2x1+16=18u.
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
The chemical formular for molecular oxygen is O2. Therefore there are 2 atoms of oxygen in molecular oxygen.
Carbon dioxide (CO2) is collected by downwards delivery because it is heavier than air. Almost all of our atmosphere is nitrogen (molecular mass = 28) and oxygen (molecular mass = 32), but CO2 has a molecular mass of 40.
61.27but add .03 so it would be 61.3
Nitrate is a molecule with one nitrogen atom and three oxygen atoms. It has a molecular mass of 62 g/mol. Nitrates are found in many different fertilisers.
No. Nitrogen is slightly less dens than air. The density of a gas is directly proportional to its molecular mass. Dry air is 78% nitrogen, 21% oxygen. Nitrogen has a molecular mass of 28 AMU. Oxygen has a molecular mass of 32 AMU. This makes air just a bit denser than pure nitrogen.
I assume you mean the molecular mass. Its molecular mass is 342.3g/mol
The relative atomic mass of hydrogen is 1 and for oxygen it's 16. This gives water (which has the formula H2O) a molecular mass of 18.
I assume you mean the molecular mass. Its molecular mass is 86.175
40 Percent. molecular mass of MgO = 24 + 16 = 40 percentage of oxygen = 100 x 16/40 = 40 .
