Hydrogen weighs 1.01 M and Oxygen weighs 16.0 M and so the atomic weight of H2O is (2(1.01)+16.0) equal to 18.02 M

Effective atomic weight of water?

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 = 18The 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

How would we determine the molecular weight for a molecule water h2o?

To determine the molecular weight of a molecule like water (H2O), you would add up the atomic weights of all the atoms in the molecule. For water, you would add the atomic weight of two hydrogen atoms and one oxygen atom, which gives you a molecular weight of approximately 18.015 atomic mass units (amu).
