Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight.
You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule.
Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1)
16+1+1 = 18
The molecular weight of water is therefore 18.
-------------------------------------------------------------------------------------
The Atomic Mass of H is 1.008, and the atomic mass of O is 16.
So 1.008*2+16=18.016

What element in the periodic table has an atomic weight of 912.2?
The Truth? Well, there is no element with that atomic weight. The highest atomic weight is 262.11 Sorry!
How is The atomic weight of an atom determined?
The atomic weight of a molecule is the weight of all the molecules in it combined. Example: H20 Hydrogen: 1.01 Oxygen: 16.00 2 hydrogens = 2.02 + 16.00 = 18.02 is the atomic weight of water.
What is the atomic weight of samarium?

What is the weight of something in the water?
Technically, the object's weight is the same. The effective or measured weight, however, will be the original weight minus the weight of displaced water.
What is chemical atomic weight?
Atomic weight = Weight of protons + Weight of neutrons
