∙ 14y agoSince each water molecular contains two hydrogen atoms, the atomic mass of oxygen is 18 - 2 = 16.

∙ 11y agoFrom the Periodic Table, hydrogen has an atomic weight of 1.00794, and oxygen has an atomic weight of 15.9994.

∙ 11y agoHydrogen has 1 proton and 0 neutron (for the most stable isotope). Oxygen has 8 protons and 8 neutrons, hence its atomic weight is 16 (sum of protons and neutrons).

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
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).
What is the mass of an hydrogen atom?
The atomic mass of Hydrogen is 1.00794 amu.
What is the atomic mass of an oxygen atom?
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 relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
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.

What is the atom weight of hydrogen?
The atomic weight of hydrogen is 1,007 94 ± 0,000 07 atomic units of 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 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.
The approximate mass of the hydrogen atom?
The conventional standard atomic weight of the hydrogen atom is 1,008 amu.
What is the atomic mass of Hydrogen Nitrogen and oxygen?
hydrogen-1g nitrogen-14g oxygen-16g
What is an atomic mass number?
Atomic mass and atomic number are two different things. Atomic mass is the mass of an atom compared to that of hydrogen. The atomic number is the atom's position in the periodic table. It's also the number of protons it has.
