The Atomic Mass of an oxygen atom depends on which isotope of oxygen you are referring to. The AVERAGE atomic mass is approximately 15.9994
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
The molecular mass of water (H2O) is 18, which means the total mass of one oxygen atom and two hydrogen atoms is 18. Since the atomic mass number of hydrogen is 1, the atomic mass of oxygen can be calculated as 16 (18 - 2).
The atomic mass of an atom is the sum of the number of protons and neutrons in its nucleus. Therefore, if an atom has 16 neutrons, its atomic mass would be the total of the protons and neutrons. For example, if the atom has 8 protons, the atomic mass would be 16 (neutrons) + 8 (protons) = 24.
Molar mass of it is 32gmol-1. It is twice than an atom.
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
an oxygen and a hydrogen atom do not weight the same
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
It isn't. Carbon is 6th on the Periodic Table and Oxygen is 8. Oxygen is the heavier element. mass of oxygen / mass of carbon 15.99g / 12.01g = 1.33 heavier than carbon
They don't contain the same number of particles because some particles are more dense than others making one atom and another atom the same mass but not have the same number of particles.
The atomic weight (not mass) of hydrogen is: [1,00784; 1,00811]; the conventional value is 1,008. The atomic weight (not mass) of oxygen is: [15,99903; 15,99977]; the conventional value is 15,999.
O = 16.00 a.m.u (atomic mass units) Mg = 24.31 a.m.u So, relatively speaking it is 1.519 times heavier
Average atomic mass of Ca = 40.1 Average atomic mass of O = 16.0 Mr(Ca)/Mr(O) = 40.1/16.0 = 2.51 Thus the calcium atom is about 2.5 times heavier than the oxygen atom.
Atomic number 8 and mass number sixteen is Oxygen
Yes. The element with an atomic number of 8 is oxygen and it's average atomic mass is 15.9994 (rounded to 16).
No all oxygen atoms do not have the same mass as you can get isotypes of the same element which are still called the same except that they can have more or less neutrons than the standard model this is why the weight is refered to as an average mass
The mass number is the sum of neutrons and protons in the atomic nucleus and is different for each isotope of any element. For example the isotope oxygen-16 has the mass number 16. The atomic weight of oxygen (not Atomic Mass) is [15,99903; 15,99977] after the IUPAC Tables - 2009. The atomic number of oxygen is 8.
