all atoms have different masses
Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.

If a hydrogen atom has a mass of 3 is it an isotope?
yes
What is oxygen to hydrogen mass ratio h2o2?
16
What has more mass 100 hydrogen atoms 4 sulfur atoms or 1 lanthanum atom?
100 Hydrogen atoms have an atomic mass of 100.794, 4 Sulfur atoms have an atomic mass of 128.26, and 1 Lanthanum atom has an atomic mass of 138.90547.
The mass of one oxygen molecule is?
Number of protons in oxygen atom: 8Mass of one proton = 1.67262158 x 10-27 KgMass of protons in one oxygen atom = 1.338097264 x 10-26 KgMass of one neutron: 1.674927293 x 10-27 KgMass 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.
Is the mass number of an atom equal to the atomic number?
Only if the atom is hydrogen-1! The mass number of the atom is equal to the sum of the numbers of protons, which is the same as the atomic number, plus the number of neutrons. The only non-radioactive atom without neutrons is hydrogen-1.
Is the mass of a hydrogen atom is different from the mass of an oxygen atom?
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.
Does water have more hydrogen or oxygen in it?
By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
Is the mass of a hydrogen atom 16 times greater than an oxygen atom?
No, it is inverse.
If the mass of one oxygen atom from water is 16amu what is the mass of one of the two oxygen atoms from hydrogen peroxide?
It's also 16 amu, ignoring the slight possibility of a different isotope.
How can that the body has 10 percent hydrogen and 63 percent of the atoms are hydrogen?
Hydrogen is the lightest of all elements, having atoms that are only a fraction of the mass of all other elements. For example, an oxygen atom has about 16 times the mass of a hydrogen atom. So while a water molecule contains 2 hydrogen atoms and 1 oxygen atom (and water makes up most of the human body), the single oxygen atom accounts for most of the mass of the molecule.
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
What is the mass and volume of the nucleus?
If you mean the nucleus of an atom, different atom have different masses - an uranium atom has more than 200 times the mass of a hydrogen-1 atom (and most of that mass is in the nucleus).
Is a hydrogen atom bigger smaller or the same size as an oxygen atom?
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
Does a carbon atom have the same mass as an oxygen atom?
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
Does an atom of carbon have the same mass of oxygen?
Carbon and oxygen or two different elements, with different masses.
Why hydrogen in water is heavier than pure hydrogen?
To clear up any confusion: water is not a mixture of hydrogen and oxygen; it is a compound. The hydrogen and oxygen are chemically bonded to each other to form a completely different substance. There are two reasons for the difference in density. First, molecules of elemental hydrogen are only weakly attracted to one another, so hydrogen exists as a gas with a lot of space between molecules. Water molecules are very strongly attracted to one another and so water exists as a liquid with much less space between molecules. Second, a water molecule contains two hydrogen atoms and one oxygen atom. One oxygen atom has about 16 times the mass of a hydrogen atom, so most of the mass of water is actually oxygen. One water molecule is about 9 times the mass of a hydrogen molecule.
How heavy is one atom of oxygen?
That depends on the atom. An atom of oxygen is 16 times heavier than a hydrogen atom (the lightest atom). Uranium atoms are over 200 times heavier than hydrogen. Regardless of what type of atom it is, a single atom won't weigh very much. well i assure you it is small and light specify the question more
