Effective atomic weight of water

Answer 1

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

Answer 2

The effective atomic weight of water, H2O, is calculated by adding the atomic weight of two hydrogen atoms (1.008 g/mol each) and one oxygen atom (16.00 g/mol). Therefore, the effective atomic weight of water is approximately 18.02 g/mol.

Answer 3

The chemical formula for water is H2O. Hydrogen has a molecular weight of 1.008 and Oxygen has a molecular weight of 15.999. The total molecular weight then is 18.015.

Answer 4

In Chemistry Equivalent weight = Molecular Mass/ n- factor = 18/1 = 18
